Description

  The present invention relates to a method, an apparatus, and a program for evaluating thermal insulation performance of a coating layer applied to a substrate. More specifically, the present invention relates to a technique for evaluating performance changes accompanying deterioration of a coating layer for heat insulation applied to a high-temperature component base material such as a combustor of a gas turbine, a moving blade or a stationary blade, for example. About.

  Heat-resistant alloys are used in high-temperature parts such as gas turbine combustors, rotor blades, and stationary blades. Thermal barrier coatings are used to protect metal substrates, especially in areas exposed to high-temperature combustion gases. It has been subjected. Here, ceramic thermal barrier coatings (also referred to as TBC) are often used as thermal barrier coatings for gas turbine combustors, etc., but the type of thermal barrier coating targeted by the present invention is limited to TBC. Therefore, hereinafter, a thermal barrier coating layer that can be an application target of the present invention is simply referred to as a coating layer including TBC.

  The coating layer usually has a thickness of several hundred microns, but exhibits excellent heat shielding performance due to the structure including many fine pores inside. However, when a coated part is used at a high temperature for a long time, the coating is gradually deteriorated and its heat shielding performance is lowered. In order to use high-temperature components in a healthy state, it is important to accurately grasp the state of deterioration of the heat shielding performance of the coating layer due to deterioration.

  For example, conventional techniques for evaluating the performance change accompanying the deterioration of the coating layer for heat shielding applied to the base material include primary diagnosis of deterioration degree based on operation history such as the number of start and stop times and operation time of the gas turbine, coating, etc. Degradation secondary diagnosis by chemical analysis in the vicinity of the interface, which is the interface between the intermediate layer and the substrate, Deterioration degree tertiary diagnosis based on ultrasonic attenuation rate, and Degradation degree fourth diagnosis by fracture strength test using micro punch test method There is a method of performing a deterioration diagnosis up to a required stage according to the degree of coating deterioration according to the four-stage procedure (Patent Document 1).

JP-A-7-310501

  When a coated part is used at a high temperature for a long time, the densification of the coating layer proceeds due to sintering, and a structure that facilitates heat transfer compared to the initial state, that is, the thermal conductivity of the coating layer increases, thereby blocking the shielding. Thermal performance is reduced. In addition, when high-temperature, high-velocity combustion gas flows on the surface of the coating layer, thinning occurs on the surface of the coating layer due to long-term use, reducing the thickness of the coating layer and improving the heat shielding performance. descend.

  However, since the method for diagnosing coating deterioration in Patent Document 1 cannot capture a decrease in heat shielding performance due to the densification of the coating layer, the thermal deterioration state that causes an increase in the substrate temperature is quantitatively determined. Cannot be evaluated. For this reason, it cannot be said that it is possible to accurately grasp the deterioration of the heat shielding performance of the coating layer due to deterioration, and there is a problem that it is difficult to say that the accuracy of performance evaluation is high.

  As shown in FIG. 1, the method for evaluating the thermal insulation performance of the coating layer of the present invention is mainly based on the three-dimensional model data for analysis and various analysis conditions. A verification line creation step (S1) for creating a verification line of the relationship between the temperature and the verification line detected by heating the part to be evaluated (part mounted on the actual machine and inspected) And an evaluation step (S2) for evaluating the change in the heat shielding performance accompanying the deterioration of the coating layer.

  Here, in this embodiment, the case where the evaluation of the heat shielding performance change is performed on the moving blade 1 of the gas turbine shown in FIG. 3 will be described as an example. In the present embodiment, the description will be made on the assumption that there are a plurality of types (models) of parts to be evaluated. In the case of the present embodiment, specifically, the shape varies depending on the stage (for example, the first stage blade, the second stage blade, the third stage blade, etc.) to which the blade 1 is attached in the combustor of the gas turbine. In consideration of the shape type of the rotor blade 1, the change in the heat shielding performance is evaluated.

  Furthermore, the method for evaluating the heat shielding performance of the coating layer of the present invention basically evaluates the change in the heat shielding performance in units of parts of the evaluation target part. In this embodiment, the plurality of parts of the rotor blade 1 are evaluated. Evaluate changes in heat shielding performance every time.

  First, the verification line creation step (S1) will be described.

  In the execution of the method for evaluating the thermal insulation performance of the coating layer of the present invention, first, the 3D model data reading unit 11a of the control unit 11 reads the 3D model data of the moving blade 1 which is the evaluation target part (S1). -1).

  In the present embodiment, the three-dimensional model data is stored as a three-dimensional model database 18 in the data server 16 that is a storage unit. The 3D model data reading unit 11 a reads 3D model data from the 3D model database 18 stored in the data server 16. Note that the three-dimensional model database 18 may be stored in the storage unit 12 which is a storage unit.

  The three-dimensional model data read in the process of S1-1 is used when calculating the temperature when the moving blade 1 is heated in the process of S1-5 by numerical analysis. As the three-dimensional model data in the present invention, an analysis mesh model is created based on actual parts.

  Specifically, first, for example, an X-ray CT scanning apparatus (specifically, for example, ACTIS800-450CT / DR system manufactured by BIR, Inc.) is used to measure the moving blade 1, and the base material including the internal structure. And scan image data of the structure of the coating layer applied to the substrate.

  For example, three-dimensional mesh data for numerical analysis based on image data obtained by measurement using an X-ray CT scan apparatus is created by first creating a polygon model from an X-ray CT scan image (specifically, Is made by Nippon Visual Science Co., Ltd. (using VGstudio MAX), and then a general-purpose 3D CAD model is created from the polygon model (specifically, for example, using INUS Technology's Rapidform XO). This is performed by creating a mesh model for numerical analysis from a three-dimensional CAD model (specifically, for example, using Pointn, manufactured by Pointwise). FIG. 4 shows an example of a three-dimensional mesh model 2 for numerical analysis of the moving blade 1 that is a part to be evaluated of this embodiment.

  Here, the process of S1-1 is performed for each type of evaluation target component (in this embodiment, the shape type). In the case of the present embodiment, specifically, the shape of the moving blade 1 varies depending on the stage (for example, the first stage, the second stage, the third stage, etc.) to which the moving blade 1 is attached in the combustor of the gas turbine. Three-dimensional model data for numerical analysis is created for each shape type of the blade 1.

  In addition, when the thickness of the coating layer cannot be accurately measured by the X-ray CT scan, the design value of the moving blade 1 is given as the thickness of the coating layer or measured by a method other than the X-ray CT scan. A value may be given, or a value normally assumed as the thickness of the coating layer of the rotor blade 1 may be given.

  Then, the 3D model data reading unit 11 a stores the 3D model data read from the 3D model database 18 in the memory 15.

  Next, the thermophysical property value setting unit 11b of the control unit 11 sets the thermophysical property value of the rotor blade 1 that is the evaluation target component (S1-2).

  The thermophysical property value set in the process of S1-2 is used when calculating the temperature when the moving blade 1 is heated in the process of S1-5 by numerical analysis. Specifically, the values of thermal conductivity, specific heat capacity, and density are set for the moving blade 1, the coating layer, and the atmosphere (atmosphere) as thermophysical values.

  In addition, the thermophysical property value set in the process of S1-2 may be a literature value, for example, or may be a value obtained by separately measuring the moving blade 1.

  Here, the process of S1-2 is performed for each type and part of the evaluation target component. In the case of this embodiment, a thermophysical value is set for each shape type of the rotor blade 1 and for each part of the rotor blade 1. For this reason, the thermophysical property value is attached with a symbol representing the type of component and the part location corresponding to the thermophysical property value.

  The thermophysical property value is set by preliminarily storing the thermophysical property value as a thermophysical property data file in the data server 16 or the storage unit 12 as storage means, and the thermophysical property value setting unit 11b reads the thermophysical property value from the file. Alternatively, the thermophysical property value may be defined in advance on the thermal insulation performance evaluation program 17, and this value may be read by the thermophysical property value setting unit 11b. The specified value may be read by the thermophysical property value setting unit 11b.

  When the operator specifies the thermophysical property value, the thermophysical property value setting unit 11b displays a message on the display unit 18 requesting the specification of the thermophysical property value at the stage of starting the processing of S1-2. The operator's designated value input via the input unit 13 is read.

  Then, the thermophysical property value setting unit 11 b stores the thermophysical property value of the moving blade 1 in the memory 15 together with a code representing the type of the evaluation target part and a code representing the part.

  Next, the heating condition setting part 11c of the control part 11 sets the heating condition of the moving blade 1 which is an evaluation object part (S1-3).

  The heating condition set in the process of S1-3 measures the detected temperature used in the process of S2-1 when calculating the temperature when the moving blade 1 is heated in the process of S1-5 by numerical analysis. Therefore, it is used when the rotor blade 1 is actually heated. Specifically, the heating position, heating diameter, heating intensity, and heating time of the moving blade 1 are set as the heating conditions.

  Here, the process of S1-3 is performed for each type and part of the evaluation target component. In the case of this embodiment, a heating condition is set for each shape type of the moving blade 1 and for each part of the moving blade 1. In the present embodiment, since the heat shielding performance change is evaluated for a plurality of parts of one moving blade 1, at least the heating position in the heating conditions differs for each part.

  For setting the heating conditions, the heating conditions may be stored in advance in the data server 16 or the storage unit 12 as a storage means as a heating condition data file, and the heating condition setting unit 11c may read the heating conditions from the file. Then, the heating condition may be defined in advance on the thermal insulation performance evaluation program 17 and this value may be read by the heating condition setting unit 11c, or the operator's designation input via the input unit 13 may be read. The conditions may be read by the heating condition setting unit 11c.

  Then, the heating condition setting unit 11 c stores the heating condition of the moving blade 1 in the memory 15 together with a code indicating the type of the evaluation target part and a code indicating the part.

  Next, the thermal resistance setting unit 11d of the control unit 11 sets the thermal resistance value of the coating layer of the rotor blade 1 that is the evaluation target component (S1-4).

  The thermal resistance value in the present invention is expressed by Equation 1 using the thickness δ of the coating layer of the rotor blade 1 and the thermal conductivity λ of the coating layer.

(Equation 1) R = δ / λ
Here, R: thermal resistance value [m ² K / W], δ: coating layer thickness [m], λ: coating layer thermal conductivity [W / mK].

  The thermal resistance value set in the process of S1-4 is used when calculating the temperature when the moving blade 1 is heated in the process of S1-5 by numerical analysis.

  And in this invention, in order to create a verification line in the process of S1-6, at least data of the combination of the thermal resistance value and the temperature when the evaluation target part is heated for each type and part of the evaluation target part Two pairs are needed. For this reason, in the process of S1-4, at least two values are set as the thermal resistance value for each type and part of the evaluation target component. Specifically, for example, a reference thermal resistance value is set based on the actual coating layer thickness and thermal conductivity of the evaluation target component, and a thermal resistance value corresponding to half or twice the reference thermal resistance value is set. It is possible to set.

  Here, the process of S1-4 is performed for each type and part of the evaluation target component. In the case of this embodiment, a thermal resistance value is set for each shape type of the rotor blade 1 and for each part of the rotor blade 1. In this embodiment, specifically, for example, when the thickness of the coating layer varies depending on the part of the part, the reference heat set based on the actual thickness of the coating layer and the thermal conductivity of the evaluation target part. The resistance value will be different.

  The thermal resistance value is set in advance by storing the thermal resistance value as a thermal resistance data file in the data server 16 or the storage unit 12 as storage means, and reading the thermal resistance value from the file by the thermal resistance setting unit 11d. Alternatively, the thermal resistance value may be specified in advance on the thermal insulation performance evaluation program 17 and this value may be read by the thermal resistance setting unit 11d, or work input via the input unit 13 The thermal resistance setting unit 11d may read a value designated by the person.

  Then, the thermal resistance setting unit 11d stores the thermal resistance value of the moving blade 1 in the memory 15 together with a code representing the type of the evaluation target component and a code representing the part.

  Next, the model temperature calculation unit 11e of the control unit 11 performs a numerical analysis of a temperature change due to heating of the moving blade 1 which is a part to be evaluated using conditions set in the processing from S1-1 to S1-4. (S1-5).

  The process of S1-5 is performed for each type of evaluation target part and for each part. In the present embodiment, numerical analysis is performed for each shape type of the moving blade 1 and for each portion of the moving blade 1.

  First, the model temperature calculation unit 11e selects one piece of data from the three-dimensional model data for numerical analysis stored in the memory 15 in the process of S1-1 and the type of the component of the data (hereinafter referred to as a calculation target type). ) Is read from the memory 15.

  Subsequently, the model temperature calculation unit 11e relates to a calculation target type from each of the thermophysical property value stored in the memory 15 in the process of S1-2 and the heating condition stored in the memory 15 in the process of S1-3. A thermophysical value and a heating condition for one of the parts (hereinafter referred to as a calculation target part) are read from the memory 15.

  And the model temperature calculation part 11e reads the thermal property value and heating conditions which have already been read while sequentially reading the thermal resistance value for the calculation target part from the thermal resistance values stored in the memory 15 in the process of S1-4. The numerical analysis (specifically unsteady heat conduction analysis) of the temperature change when the moving blade 1 is heated is performed for each type, part, and thermal resistance value of the evaluation target parts (specifically, unsteady heat conduction analysis) For example, ANSYS made Fluorent).

  The model temperature calculation unit 11e stores the temperature calculated as a result of the numerical analysis (hereinafter referred to as model temperature) as combination data of the thermal resistance value and model temperature for each type of evaluation target part and for each part. Are stored in the storage unit 12 and the memory 15.

  Next, the test line creation unit 11f of the control unit 11 creates the test line 3 by using the combination data of the thermal resistance value of the moving blade 1, which is the evaluation target component derived in the process of S1-5, and the model temperature. (S1-6).

  The test line 3 is a curve representing the relationship between the thermal resistance value R and the component temperature T as shown in FIG. The test line 3 is created for each type and part of the evaluation target part. In the case of the present embodiment, the test line 3 is created for each shape type of the moving blade 1 and for each part of the moving blade 1.

  The calibration line creation unit 11f is selected from the combination data of the thermal resistance value and the model temperature for each type and part of the evaluation target part stored in the storage unit 12 and the memory 15 which are storage means in the process of S1-5. All the combination data of the thermal resistance value and the model temperature relating to a specific type and part are read from the storage unit 12 or the memory 15.

  Then, the test line creation unit 11f performs regression processing using a plurality of combination data of the thermal resistance value R and the model temperature (corresponding to the temperature of the part) T, and determines a test line as a regression curve of the combination data. To do.

  Then, the verification line creation unit 11f stores the constants a and b of the verification line 3 for each type and part of the evaluation target part in the memory 15.

  The above-described verification line creation step (S1) is performed only once for a specific part of a specific type of the evaluation target part in order to generate the verification line 3 for the part of the type. And the process of the following evaluation steps (S2) is performed using the verification line 3 created by this certification line creation step (S1). When the verification line created by the processing of the verification line creation step (S1) is used in the continuous inspection work of the evaluation target parts, the constants a and b of the verification line 3 are stored in the storage unit 12 or the storage means. It may be stored in the data server 16.

  Subsequently, the evaluation step (S2) will be described. The process of this evaluation step (S2) is a process used in inspection work for judging the necessity of repair or replacement of parts mounted on the actual machine, and heating the parts mounted on the actual machine. The temperature is measured and the state of the part is evaluated using the verification line 3 created in the calibration line creation step (S1).

  As an evaluation step (S2), first, the detected temperature reading unit 11g of the control unit 11 detects the temperature detected by measuring the temperature when the evaluation target component (the component mounted on the actual machine) is actually heated. Data (hereinafter referred to as detected temperature data) is read (S2-1).

  Heating of the moving blade 1 for obtaining detected temperature data of the evaluation target component is performed according to the heating condition set in the process of S1-3. The heating of the rotor blade 1 and the measurement of the temperature are performed for each heating position set as a heating condition, that is, for each part to be evaluated. The heating of the rotor blade 1 is specifically performed using a laser, for example. The temperature is measured using an infrared sensor, for example.

  For the detected temperature data, the detected temperature obtained by measurement is stored in advance in the data server 16 or the storage unit 12 as storage means as a detected temperature data file, and the detected temperature value is read from the file as the detected temperature reading unit 11g. May be read, or the detection temperature reading unit 11g may read a value designated by the operator input via the input unit 13.

  Here, it is necessary to associate the detection line for each type and part of the evaluation target part created in the process of S1-6 with the detection temperature data. For example, in the detection temperature data file, individual detection temperature data For example, a code (so-called flag) for identifying the type and part of the measured part is given, or when the operator inputs the value of the detected temperature via the input unit 13, the type and part of the part are specified. Or specify it.

  Further, when there are a plurality of parts that are actually inspected and have the same type (model; shape type in the present embodiment) as parts to be evaluated, for example, in the detection temperature data file, individual detection temperature data In addition, a component identification code (so-called ID number) that is measured is assigned, or the component identification code is also designated when the operator inputs the value of the detected temperature via the input unit 13. To do.

  Then, the detected temperature reading unit 11g stores the value of the detected temperature for each part in the memory 15 in association with the type of the evaluation target component together with the ID number of the component, if necessary.

  Next, the thermal resistance calculation unit 11h of the control unit 11 calculates the thermal resistance value of the evaluation target component using the verification line 3 created in the process of S1-6 and the detected temperature read in the process of S2-1. Calculate (S2-2).

  The process of S2-2 is performed for each part part for each part that is mounted on the actual machine and that is to be inspected. In the case of this embodiment, the thermal resistance value is calculated for each part of the moving blade 1 for each moving blade 1 mounted on the actual machine.

  Specifically, the thermal resistance calculation unit 11h first reads from the memory 15 the type of one specific component from the detected temperature data stored in the memory 15 in the process of S2-1. Hereinafter, the type of component read at this stage is referred to as a calculation target type.

  Subsequently, the thermal resistance calculation unit 11h selects one part (hereinafter referred to as a calculation target part) from the detected temperature data for each part of the calculation target type among the detection temperature data stored in the memory 15 in the process of S2-1. Value).

  Next, the thermal resistance calculation unit 11h calculates the calculation target for the type of calculation target from the constants a and b of the test line 3 for each type of the evaluation target component and for each part stored in the memory 15 in the process of S1-6. The constants a and b of the part are read from the memory 15.

The heat resistance calculating portion 11h, the thermal resistance by substituting the value T ₁ of the temperature detected by the calculation target region on the component temperature T in terms of the constants of Equation 2 a, b values to values read from the memory 15 R is calculated, and the calculated thermal resistance value R ₁ is stored in the memory 15.

  The thermal resistance calculation unit 11h calculates the thermal resistance value R for each part related to one specific part (calculation target type) for all parts, and the thermal resistance for each part also for other parts (calculation target type) The value R is calculated.

  Next, the heat shield performance evaluation unit 11i of the control unit 11 needs to repair or replace the component by evaluating the heat shield performance of the evaluation target component based on the thermal resistance value calculated in the process of S2-2. Sex is judged (S2-3).

Evaluation of the thermal barrier performance is performed by comparing the thermal resistance R ₁ and the critical heat resistance was calculated in S2-2 Rcri. The critical thermal resistance value Rcri is a value of the thermal resistance that the coating layer of the evaluation target component should have as a minimum, and is determined by the worker in consideration of the material of the base material, the installation location of the evaluation target component, the environment such as the ambient temperature, and the like. It is set in advance.

  The limit thermal resistance value Rcri may be defined in advance on the thermal insulation performance evaluation program 17 and read by the thermal insulation performance evaluation unit 11i, or an operator input via the input unit 13 The heat shielding performance evaluation unit 11i may read the designated value. The limit thermal resistance value Rcri may be a uniform value regardless of the type of the evaluation target component, may be set for each type of the evaluation target component, or may be set for each part of the evaluation target component. You may do it.

Heat insulating performance evaluation unit 11i, first, reads the thermal resistance R ₁ of different sites of the evaluation target part that is stored in the memory 15 in the processing of S2-2 from the memory 15.

Subsequently, a thermal barrier performance evaluation unit 11i compares the thermal resistance R ₁ different sites of the evaluation target part and critical heat resistance Rcri. In the case of R ₁ > Rcri, it is determined that the coating layer at the part of the evaluation target component has the required thermal resistance. On the other hand, in the case of R ₁ ≦ Rcri, the coating layer of the part does not have the required thermal resistance, that is, the part does not maintain the required thermal resistance. Judge that it is necessary to replace itself.

And the thermal-insulation performance evaluation part 11i performs the said process about all the parts about all the components. When R ₁ ≦ Rcri, for example, the display unit 14 displays the ID number of the component, the type of the component, the location of the component, and the thermal resistance value R ₁ to repair or replace the component with respect to the operator. Is notified, and the process ends (END).

  According to the method, apparatus, and program for evaluating the thermal insulation performance of the coating layer configured as described above, the thermal insulation performance of the coating layer can be improved by heating the evaluation target component under a heating condition arbitrarily set within a feasible range. Evaluation can be made. In addition, the heat shielding performance of the coating layer can be evaluated by heating the evaluation target component under heating conditions arbitrarily set within a range that does not damage the coating layer or the base material. Furthermore, even when the shape of the evaluation target part is complicated or when the coating application conditions and the thermophysical property values differ depending on the part part, it is possible to perform an evaluation based on them.

  In addition, although the above-mentioned form is an example of the suitable form of this invention, it is not limited to this, A various deformation | transformation implementation is possible in the range which does not deviate from the summary of this invention. For example, in the present embodiment, the case where the evaluation of the thermal insulation performance change is performed on the moving blade 1 of the gas turbine is taken as an example, but the evaluation target of the thermal insulation performance change is not limited to this, and the base material and The present invention can be applied to any component having a coating layer for heat insulation.

  Further, in the present embodiment, an example has been described on the assumption that there are a plurality of types (that is, shape types) of the moving blade 1, but this is not a limitation, and there is only one type of evaluation target component. It can be used even if it exists. Furthermore, in this embodiment, the example on the assumption that the evaluation is performed for each of a plurality of parts of the moving blade 1 has been described. However, the present invention is not limited to this, and even if there is one part to be evaluated. It can be used.

  Here, the thermal insulation performance evaluation apparatus for a coating layer according to the present invention is configured to further include an X-ray CT scanning device 21, a laser oscillation device 22, a robot 23, and a non-contact thermometer 24, as shown in FIG. You may make it.

  The X-ray CT scanning device 21 is for measuring the moving blade 1 in connection with the above-described processing of S1-1 and converting the shape including the internal structure into three-dimensional digital data. Is for acquiring scanned image data of the moving blade 1.

  Then, the three-dimensional digital data 25 (that is, the scanned image data) of the shape of the moving blade 1 acquired by the X-ray CT scanning device 21 passes through the process described in the process of S1-1 (in the case of the present embodiment). Specifically, it is processed and used as data of a three-dimensional mesh model 2) for numerical analysis. In the present embodiment, the three-dimensional digital data 25 is temporarily stored in the data server 16 and processed as the three-dimensional mesh model 2 for numerical analysis through the process described in the process of S 1-1. It is accumulated again in the server 16.

The laser oscillation device 22 is a device for heating the surface of the coating layer of the rotor blade 1 in association with the above-described processing of S2-1. As the laser 22a, a CO ₂ laser or a semiconductor laser is specifically used in consideration of stably heating the surface of the rotor blade 1.

  Here, in the heating of the surface of the moving blade 1 by the laser oscillation device 22, it is necessary to accurately follow the heating conditions set in the processing of S1-3 and to ensure the accuracy of numerical analysis for the three-dimensional model. Considering the ease and ease, it is desirable that the laser 22a is always irradiated at an equal distance from the vertical direction with respect to the surface of the rotor blade 1.

  However, the heating position, the heating diameter, the heating intensity, and the heating time are accurately followed and the entire surface of the moving blade 1 having a curved surface is always vertically and equidistant. It is very difficult to control the irradiation position, direction, time, etc. of the laser 22a by manual operation, and it is not desirable from the viewpoint of ensuring accuracy.

  Therefore, the robot 23 is used to control the irradiation position, direction, time, etc. of the laser 22a. Specifically, a mechanical handling device that operates under computer control is used as the robot 23. Furthermore, if necessary, a stage 26 on which the moving blade 1 that is an evaluation target component is placed may be provided, and the stage 26 may be linked to the operation of the robot 23.

  Then, in the operation control of the robot 23 (and the stage 26 if necessary), the heating conditions set in the process of S1-3 and the tertiary of the shape of the moving blade 1 obtained by the X-ray CT scanning device 21 are used. By using the three-dimensional mesh model 2 based on the original digital data 25, it is possible to accurately control the irradiation position, direction, time, and the like of the laser 22a in accordance with the heating conditions and the surface shape of the moving blade 1.

  In order to irradiate the laser 22a via the robot 23, a laser oscillation device may be incorporated into the tip 23a of the arm of the robot 23 so that the laser oscillation device and the robot are integrated. As in the example shown in FIG. 6, the laser transmitter 22 and the robot 23 may be configured separately. In the case of the example shown in FIG. 6, the laser from the laser oscillation device 22 is transmitted to the distal end portion 23a of the robot arm through, for example, the optical fiber 22b.

  The non-contact thermometer 24 measures the temperature when the moving blade 1 is heated by the laser 22a by the laser oscillation device 22, that is, the surface temperature of the coating layer, in association with the above-described processing of S2-1 and is detected by measurement. This is for outputting temperature data (ie, detected temperature data). As the non-contact thermometer 24, specifically, a radiation thermometer or a thermography is used.

  When a radiation thermometer is used as the non-contact thermometer 24, the radiation thermometer is a device that performs one-point measurement. Therefore, the temperature measurement point by the radiation thermometer 24 is moved in accordance with the irradiation of the laser 22a by the robot 23. I will let you.

  On the other hand, when thermography is used as the non-contact thermometer 24, it is possible to acquire a thermal image for a certain region, and the certain region is finely controlled and moved in accordance with the irradiation of the laser 22a by the robot 23. There is no need. In addition, it has been confirmed by the inventors that the laser irradiation point and the point at which the maximum temperature is detected tend not to coincide with each other, and the maximum temperature is measured by measuring temperature in units of a certain area using thermography. It is preferable to detect points from the viewpoint of ensuring accuracy.

In consideration of the reflection of the laser 22a on the surface of the coating layer, the non-contact thermometer 24 includes a CO ₂ laser wavelength (about 10.6 [μm]) and a semiconductor laser wavelength (about 800 [nm]). It is desirable to use equipment that can detect no wavelengths.

  The detected temperature data related to the moving blade 1 measured and output by the non-contact thermometer 24 is stored in the data server 16 or the storage unit 12 as a detected temperature data file, for example.

  According to the above-described apparatus further including the X-ray CT scanning device 21, the laser oscillation device 22, the robot 23, and the non-contact thermometer 24, the heat shielding performance can be evaluated while ensuring the accuracy of various measurements. It becomes possible.

  An embodiment of verification of the effectiveness of the thermal barrier performance evaluation method, apparatus and program of the present invention will be described with reference to FIGS.

  Specifically, in this embodiment, as shown in FIG. 7, the shielding member of the present invention is used by using a test body 30 that simulates a part of the back side of the blade 1 of the gas turbine (a part surrounded by a broken line in the figure). The effectiveness of thermal performance evaluation was verified.

  As the test body 30 of this example, a base material 31 having a thin cylindrical shape with an outer diameter D = 30 [mm] and a thermal barrier coating layer 32 applied on the outer peripheral surface was used.

  In the present embodiment, the base material 31 has three thicknesses of 1, 2, 3 [mm] (the inner diameter d of the base material 31 is 28, 26, 24 [mm], respectively). Moreover, the thickness of the thermal barrier coating layer 32 was set to three types of 0.1, 0.2, and 0.3 [mm].

  Moreover, in the present Example, the test body 30 was heated using the laser. Specifically, the laser is irradiated to a quarter of the outer peripheral surface of the test body 30 (that is, the outer peripheral portion corresponding to the central angle θ = 90 degrees; hereinafter referred to as the laser irradiation range 33). did.

  In consideration of the fact that the laser heating needs to be set to such a condition that the thermal barrier coating does not sinter, the surface temperature of the thermal barrier coating layer 32 is about 400 [° C.] at maximum. The heating intensity is 0.6 [W], the heating region diameter is 1 [mm], and the laser moving speed is 5 [mm / sec] in the circumferential direction of the outer peripheral surface of the test body 30.

  The thermophysical values of the base material 31 and the thermal barrier coating were based on literature values (Fujii et al .: Thermal characteristics of coating layers for gas turbines-1st report. -, Report of Central Research Institute of Electric Power (W97017), 1998). The emissivity of the surface of the thermal barrier coating layer 32 was 1.0. The atmosphere inside and outside the test body 30 was air.

  The temperature change at the temperature measurement point 35 until the laser reached the heating end point 34b from the heating start point 34a was calculated by unsteady heat conduction analysis. The temperature measurement point 35 was set to the central point of the laser irradiation range 33 (that is, the point corresponding to the central angle θm = 45 degrees from the heating start point 34a).

  First, the thickness of the base material 31 was fixed to 2 [mm] and the thickness of the thermal barrier coating layer 32 was changed, and the calculation result shown in FIG. 8 was obtained. From this result, the temperature at the temperature measurement point 35 reaches the maximum temperature in about 0.05 [seconds] after the center of the laser passes (denoted as “laser passage point” in the figure), and the thermal barrier coating layer 32 (in the figure “ It was confirmed that the maximum temperature value greatly differs depending on the difference in thickness of TBC.

  And the verification line shown in FIG. 9 was obtained from the relationship between the maximum temperature shown in FIG. 8 and heat insulation performance.

  On the other hand, in actual measurement using the test body 30, the surface of the thermal barrier coating layer 32 is laser-heated under the same conditions as the heating conditions in the above analysis, and the thermal barrier coating layer 32 measured at the temperature measurement point 35 is measured. The thermal barrier performance of the thermal barrier coating was determined using the surface temperature and the calibration line shown in FIG.

  Here, the measurement accuracy of a non-contact thermometer such as a radiation thermometer or a thermography generally used as a measuring device for the surface temperature of the measurement object should be within a range of about ± 2 [%] with respect to the measured temperature. Is common. For this reason, as shown in FIG. 8, when the surface temperature of the thermal barrier coating layer 32 is about 400 [° C.], the measurement error is considered to be within a range of about ± 8 [° C.].

  In FIG. 8, when the thickness of the thermal barrier coating layer 32 is 0.2 [mm] and 0.3 [mm], the maximum temperature difference is about 80 [° C.]. For this reason, when the same measurement is performed with the non-contact thermometer using the test body 30 of the present embodiment, an error corresponding to ± 0.01 [mm] is included when converted to the thickness of the thermal barrier coating layer. I thought it would be.

  Here, according to the literature (Morinaga et al .: Development of TBC thermal insulation performance nondestructive evaluation method-1st report, Proposal of TBC thermal insulation performance evaluation method-, Central Research Institute of Electric Power Industry report (W97021), 1998) From the result of the simulated heat transfer simulation, it is said that the surface temperature of the substrate changes by 1 [° C.] when the thickness of the thermal barrier coating layer changes by 0.0023 [mm], and 0.01 [mm] It was thought that the change in the thickness of the thermal barrier coating layer resulted in a change in the substrate temperature within 5 [° C.].

  Results of existing studies (Watanabe et al .: Thermal flow analysis of 1300 ° C class gas turbine first stage rotor blade internal cooling-1st report-Analysis of high Reynolds number field in straight pipe flow path with orthogonal ribs-Report by Central Research Institute of Electric Power Industry (W00006) , 2000), the allowable temperature error when evaluating the life of gas turbine high-temperature components is within ± 20 ° C, and the error within 5 ° C for the substrate temperature is within this range. It was confirmed that it fits well within.

  From the above results, the thermal barrier performance evaluation method of the coating layer according to the present invention is acceptable when performing life evaluation of high-temperature components of a gas turbine by introducing an apparatus capable of measurement as in the present embodiment. It was confirmed that it is possible to perform an evaluation that falls within a possible temperature error.

  Next, the calculation result shown in FIG. 10 was obtained by analyzing the case where the thickness of the thermal barrier coating layer 32 was fixed to 0.2 [mm] and the thickness of the base material 31 was changed. From this result, when the thickness of the base material 31 is 2 [mm] and 3 [mm], there is no significant difference in the maximum temperature, whereas when the thickness is 1 [mm], the maximum temperature is 8 [° C]. It was confirmed that it was higher.

  From this result, when the influence of the thickness of the base material 31 is not taken into consideration, the difference in the thermal barrier performance of the thermal barrier coating layer despite the difference in the maximum temperature due to the difference in the thickness of the base material. It was thought that there was a difference in the maximum temperature due to this, which could cause measurement errors.

  In the present invention, a three-dimensional model (that is, a three-dimensional mesh model for numerical analysis) of the moving blade 1 to be measured is created and used for numerical analysis, and the numerical analysis is performed on the part of the moving blade 1. Since the thickness of the base material for each part of the rotor blade 1 is taken into consideration in the numerical analysis in such a way as to be performed every time, the above-described measurement error is eliminated and the heat shielding performance having high accuracy is evaluated. Is confirmed to be possible.
