Abstract
The invention discloses a method for measuring corrosion damage based on a solid model, belonging to the technical field of corrosion damage measurement. The method comprises the following steps: firstly, acquiring a solid model having a corroded surface by utilizing a gel material; and then, acquiring corrosion damage parameters by measuring the solid model. The invention also discloses a measuring device which comprises a base plate used for bearing a corrosion sample, the gel material and a frame arranged on the periphery of the corrosion sample and used for containing the gelled material. Compared with the prior art, the invention has the advantages that the precision is higher, the operation process is simple, and the corrosion damage caused by both local corrosion and general corrosion can be measured.
Description
Technical field
The present invention relates to the corrosion damage field of measuring technique, belong to physical department, measure by International Patent Classification (IPC) (IPC) division; Test big class, by means of the chemistry of measuring material or physical property is tested or the analysis of material group, the weatherability of test material, corrosion-resistant or resistance to light group.
Background technology
The corrosion stability of material is that the important quality of decision systems and parts mission life under etching condition guarantees one of parameter.Corrosion test is to measure certain material corrosion proof main means under the particular etch condition.Carry out corrosion test, except will also determining the measurement parameter and the measuring method thereof of corrosion damage according to research purpose selection and confirmed test method and the test condition.
Existing corrosion damage measuring method has comprised visual examination, mass method, the thick measurement of mistake, pitting depth survey, electric-resistivity method etc.These methods are all directly at corrosion sample itself, though kind is many, but exist all that operating difficulties, measurement result degree of accuracy are lower, the corrosion damage data obtained not comprehensively, the corrosion damage degree comparatively is difficult to accurately variety of issues such as mensurations in difficulty, maximum corrosion damage position more everywhere, and these methods can't be taken into account the measurement that local corrosion damage and uniform corrosion are damaged.
Summary of the invention
The problem to be solved in the present invention is to overcome defectives such as operating difficulties, the degree of accuracy corrosion damage data lower, that obtain that have the existence of corrosion damage measuring method now are not comprehensive, provide a kind of precision higher, simple, and can take into account the corrosion damage measuring method of local corrosion and general corrosion simultaneously.
The present invention is by the following technical solutions:
A kind of corrosion damage measuring method based on solid model at first utilizes Binder Materials to obtain the solid model of corrosion surface, obtains the corrosion damage parameter by measuring solid model then.
Corrosion damage measuring method based on solid model of the present invention, directly corrosion surface is not measured, but make the solid model of corrosion surface by Binder Materials, then by measurement obtains the parameters such as quantity, distribution, shape, surface area and volume of corrosion damage to model.Compared to existing technology, the inventive method has the following advantages:
1) the inventive method generates the solid model of the part that is corroded by Binder Materials, the corrosion damage that feasible script is depressed in the surface that is corroded becomes the solid model that shows especially, make local corrosion parameter (as the pitting degree of depth, shape etc.) be easy to accurate measurement, and this is to have now with the local corrosion measuring method that once had to be difficult to accomplish.
2) solid model that the inventive method generated not only can be used for accurately measuring the various parameters of single local corrosion damage, and can be used for the degree of the distribution of the damage of local corrosion everywhere and corrosion damage is carried out simply and intuitively relatively and statistics, and can carry out the evaluation at serious position of corrosion damage.The local corrosion measuring method that has now and once had is difficult to realize above target for the corrosion surface of complexity.
3) the inventive method can be used for the damage measurement of local corrosion and general corrosion simultaneously, and corrosion damage measuring method existing and that once had is difficult to take into account both.
Description of drawings
Fig. 1 is the corrosion damage measurement mechanism structural representation based on solid model of the present invention described in the embodiment, and wherein, 1 is base plate, and 2 is frame, and 3 are the corrosion sample, and 4 is Binder Materials;
Fig. 2 is the enlarged drawing of the sample 3 of corrosion described in the embodiment;
Fig. 3 is the enlarged drawing of the solid model that obtains in the embodiment.
Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
The present invention adopts device as shown in Figure 1 to implement the corrosion damage measuring method based on solid model of the present invention, and this device comprises and is used to place base plate 1, the Binder Materials 4 of corrosion sample 3 and places corrosion sample periphery to be used to hold the frame 2 of Binder Materials.
When using said apparatus to carry out the corrosion damage measurement, corrosion sample 3 to be measured is placed on the base plate 1, the corrosion surface that needs to measure is towards the top; Frame 2 is placed on the base plate 1; In frame 2, add Binder Materials 4; After treating that Binder Materials 4 is solidified, remove frame 2, take out solid model; Solid model is measured and added up.The corrosion sample 3 enlarged drawing as shown in Figure 2, there is corrosion damage in upper surface; By said method, the corrosion damage that is depressed in corrosion surface originally is converted to the solid model that shows especially, as shown in Figure 3, and the solid model that this shows especially is measured and add up all very simple and convenient, and the measuring accuracy height.
In the said apparatus, described frame 2 and base plate 1 can be made preferable alloy or plastics by the solid material that can not glue the viscose gel material; The corrosion sample that described Binder Materials 4 can be measured as required and the size of corrosion damage are selected, in principle be difficult for sticking glutinous, fine and smooth, the single convenience of color observe, be easy to moulding and solidify after not cracky be advisable preferred gypsum or greasy filth.
For the ease of taking out solid model and being convenient to follow-up measurement, above-mentioned base plate 1 backplate surface is provided with and corrodes the depression that sample 3 shapes adapt, and the degree of depth of depression equals to corrode the thickness of sample 3.
The corrosion sample that that corrosion damage measuring method based on solid model of the present invention has is simple to operate, device is easy to design is low with manufacturing, cost, be applicable to different sizes and shape, be applicable to that dissimilar corrosion damages measures, measures that the corrosion damage data class of gained is complete, measuring process simple and directly perceived, measurement result precision advantages of higher, be fit in the laboratory corrosion damage of all kinds of corrosion samples be measured and evaluation.
