Abstract
A study is made of the nature of structural changes and failure mechanisms for high-temperature alloys based on nickel with different crystal structure (directional and single crystal) with multilayer (including an outer ceramic layer) coatings based on nickel with high-temperature thermal cycling loading in a gas stream. The dependence of thermal cycling endurance of the metal-coating composite on crystal structure of the protected alloy and its application technology is established.
