Abstract

The process of surface modification in the ion-plasma installation MAP-3 is considered. It is shown that with the chosen parameters of the modification process, the temperature of the samples does not exceed the tempering temperature of the compressor steels EP866 and EI961. Metallographic and microspectral studies of the surface layer of the samples after modification have been carried out. Modified samples were tested for resistance to salt corrosion by the VIAM method at a temperature of 600°C.
