Abstract

The x-ray method is used to determine residual macrostresses in the surface layer of protective coatings on high-temperature alloys. Coatings deposited by the high-energy vacuum-plasma (HEVP) method were subjected to diffusion annealing and mechanical treatment. The calculated and experimental values of residual thermal stresses in the coatings are compared.
