Overview
Functionally graded (FG) materials are developed for using as the impact-resistant and protective coatings for the metallic elements which are subjected to large thermal loads in a high-temperature environment (up to the temperatures of the order of 1,000 K). Usually, the functionally graded coating is synthesized by the “layer by layer” technology with different volume content of ceramics, thus producing the desired through-thickness gradient of the thermal and mechanical characteristics of a coating [1]. In order to evaluate the behavior of a coating under a large thermal load, it is necessary to perform the reliability testing of a coating–metal assembly. Laser thermal shock is one of the most effective methods for thermal reliability testing of the functionally graded coatings. In this method, a coating is irradiated by a focused power laser beam, and the temperature of a coating may rise at the rate of the order of 106 K/s [2]. The nonuniform temperature field causes...
