Abstract

The paper presents the results of studying the structure and physical and mechanical properties of a Ni–Co–Cr–Al–Y heat-resistant intermetallic compound coating, formed by the method of the high-energy plasma powder spraying on the working surfaces of turbine blades of a gas turbine engine in the initial state and after completing the designed resource (within ~28000 h), as part of a GTE-45-3 power unit of a thermal power plant (ОАО Yakutenergo).
