FIELD: metallurgy.
SUBSTANCE: invention refers to machine engineering and metallurgy and can be employed in aircraft building and power turbine building, mainly for salt corrosion protection of details of gas-turbine engine compressor. The method incorporates successive applying the first layer of condensed coat on the surface of a detail; also this layer is composed out of alloy on base of nickel containing cobalt, chromium, aluminium, and yttrium, and applying the second layer of coat which is obtained by means of successive applying slip coats - silicon, phosphate and silicon again; after applying each coat it is dried and thermo-treated at the temperature of 350 - 450°C during 5-20 minutes.
EFFECT: creation of coat resistant to salt corrosion while maintaining mechanical properties of steel details of mechanisms with temperature of annealing below 600°C.
