Study on Microstructure and Properties of Coating on the Surface of Fe14Mn6Si5Ni Alloy

Abstract:

In this paper, the coating was prepared by the slurry pack cementation on the surface of Fe-14Mn-6Si-5Ni alloy at 900°C for 10 h. A slurry pack cementation mixture was composed of Cr₂O₃ used as chrominizing source, pure Al powder as reducer, an activator of NH₄Cl and albumen (egg white) as cohesive agent. The microstructure, wear resistance and corrosion resistance of coating has been studied. The results showed that the microstructure of the coating is composed of solid solution with Al and Cr; the microhardness of coating with a value of 460 HV was 1.4 time than that of the matrix alloy, friction coefficient of the coating was 0.35, 1/2 of that of matrix alloy, and the rate of corrosion of coating was lower one order of magnitude than that of the FeMnSi based alloy.
