Changes in the structure, phase and chemical composition of two-layer heat-resistant ceramic coatings and surface layers of the ZhS6U alloy under the coating have been studied during high-temperature annealing and creep. Additional coating of ceramics containing 40% Y 2 O 3 , 40% ZrO 2 , 10% Cr 2 O 3 , 10% Al 2 O 3 increases the creep resistance of the heat resistant alloy. Il. 2, bibliography: 5 titles.
