The wearing processes of heat-and corrosion-resistant nickel alloy KhN58KVTYuMB ChS-70VI without and with electron-beam coatings of Co-23%Cr-12%Al-0.15%Y alloy are considered under high-temperature oxidation and sulfide-oxide corrosion conditions. Additional aluminizing by circulation gas method is suggested to improve the anticorrosion properties of coatings and protect the surfaces of internal cooled working and nozzle blands turbomachines.
