Abstract

The invention relates to a device and a method in the testing technical field, in particular to a synchronization testing device and a testing method of thermal barrier performance and thermal shock performance of a thermal barrier coating. The method enables the thermal barrier performance and the thermal shock performance of the thermal barrier coating to be obtained simultaneously and temperature change of a test sample in a thermal shock performance testing process to be recorded in detail, and facilitates deep analysis of the thermal shock failure mechanism of the test sample. According to the testing method, heating and cooling methods of the test sample can be determined as needed, and therefore serving conditions of a thermal barrier coating component can be simulated close to reality, quality of the thermal barrier coating can be tested accurately, the service life of the thermal barrier coating can be estimated accurately, and further the spraying effect of the serving component under a high-temperature working condition can be effectively estimated.

Description

technical field [0001] The invention relates to a device and a test method in the technical field of testing, in particular to a device for synchronously testing thermal barrier performance and thermal shock performance of a thermal barrier coating and a test method thereof. Background technique [0002] Thermal barrier coatings are generally a coating system composed of a surface ceramic coating and an intermediate metal bonding layer. Using flame spraying, plasma spraying, electron beam physical vapor deposition and other technologies, thermal barrier coatings are prepared on the surface of high-temperature heating parts, and the excellent thermal barrier effect of thermal barrier coatings is used to protect the base material of the heating parts, thereby increasing the working temperature of the heating parts. Thermal barrier coating technology is widely used in aerospace, gas power generation and other fields. At present, the application of thermal barrier coating techno...
