The microstructural aspects of abrasive wear resistance in composite electron beam clad coatings

The effect of microstructure and phase composition of composite coatings based on manganese-containing or nickel-containing austenitic steel and containing either 10 wt.% TiC or 15 wt.% WC on the abrasive wear resistance has been studied. Both post-deposition heat treatment and self-aging in the course of deposition served to improve the relative wear resistance coefficient by 38-42 and 5-12% for Fe-20%Mn-4%V-4%Mo + 15%WC and Fe-20%Ni-4%V-4%Mo + 15%WC coatings, respectively.
