（従来の技術）

用機器への適用が研究されている。(Prior Art) A high-temperature heat-resistant member, for example, a turbine blade of a gas turbine, has a structure in which a thin ceramic layer with a thickness of about 0.3M is formed as a thermal barrier coating layer on the surface of a base material such as a heat-resistant alloy. High-temperature heat-resistant members having such a structure can be used for long periods of time by protecting the base material from high temperatures exceeding the durability limit with a thermal barrier coating layer, and therefore, application to various large-scale industrial equipment is being studied.
ところで、遮熱コーティング層は例えばＹ２０！安定化
ＺｒＯ２のプラズマ溶射により形成されるが、その品質
管理の方法は必ずしも確立されておらず、信頼性高く使
用できるまでには至っていない。By the way, the thermal barrier coating layer is, for example, Y20! Although it is formed by plasma spraying of stabilized ZrO2, its quality control method has not necessarily been established, and it has not reached the point where it can be used with high reliability.

招く。このため、遮熱コーティングを施工した後研磨を
施すが、その研磨度を検定する適当な手段がない。Regarding the thermal barrier coating layer, there are several factors that must be quality controlled, but as described below, control of the surface condition is important from a fluid dynamic point of view. Immediately after plasma spraying, the thermal barrier coating layer has a surface roughness of 50 to 60-. If left as is, it will cause turbulence when high-temperature gas flows over its surface at high speed, resulting in adverse effects such as an increase in gas flow resistance or heat transfer coefficient. For this reason, polishing is performed after applying the thermal barrier coating, but there is no appropriate means to verify the degree of polishing.
この研磨度の検定手段として、例えば表面粗さ計を用い

非破壊でかつ簡便な方法が要求される現場での判定に利
用することは困難である。Possible methods for testing the degree of polishing include, for example, using a surface roughness meter or microscopic observation of the cross section.
It is difficult to use it for on-site determination, which requires a non-destructive and simple method.

記蛍光物質としては青緑色の蛍光を発するものを用いる
ことがＪＩＳで規定されている。It is also conceivable to apply fluorescent flaw detection, which has traditionally been widely used as a method for detecting surface defects. In this fluorescent flaw detection, fine particles of fluorescent material are applied to the surface to be detected and cleaned, and then the fluorescent material remaining in the surface defects is irradiated with ultraviolet light to emit light to clarify the defects. However, this fluorescent flaw detection method cannot be used to verify the degree of polishing of a thermal barrier coating layer made of Y2O3-stabilized ZrO2 for the reasons described below. That is, JIS specifies that the fluorescent material should be one that emits blue-green fluorescence.

ない。On the other hand, Y2O3-stabilized ZrO2 itself also emits fluorescence when irradiated with ultraviolet rays, and its emission color changes from blue-white with phosphorescence of ZrO2 alone to dark orange with an increase in red as the solid solution amount of Y2O3 increases. However, the brightness is low and the clarity is not sufficient. For this reason, the base Y203 stabilized Zr
The degree of polishing cannot be verified because the luminescence between O2 and the fluorescent material remaining in the defect (recessed portion after polishing) is not clearly distinguished.

It is clearly different from the blue-green fluorescence emitted when the fluorescent material used in fluorescent flaw detection is irradiated with ultraviolet light. Therefore, Eu

If a fluorescent material is applied to the surface of a thermal barrier coating layer made of O2, washed, and then irradiated with ultraviolet rays, it is possible to clearly distinguish between the two types of light emission, and the area where light emission due to the fluorescent material is occurring is visible after polishing. Since the surface area corresponds to the area of the recess, the degree of polishing of the surface can be easily and non-destructively verified.

かたけ観察され、研磨が良好であることが確認できた。After applying a fluorescent substance to the surface of this high-temperature heat-resistant member and washing it off, the surface was observed by irradiating ultraviolet light with a wavelength of 254 nm. As a result, a slight amount of blue due to the luminescence of the fluorescent substance was observed in the bright orange color due to the luminescence of the thermal barrier coating layer, which is the base material, and it was confirmed that the polishing was good.
