Abstract

We present the methods and results of an experimental investigation of the thermal cyclic life of five types of plasma heat-resistant thermal-barrier coatings on the combustion chamber of a gas turbine in a high-temperature gas flow. We analyze the thermal stressed and strained state of an element of the fire tube for three types of coatings by performing several variants of numerical calculations and study the influence of coatings on the thermal stresed and strained state of the composite and the character of its damage.
