%X Surface modification is one of important research fields of tribology,and spray-welding is a widely used surface modification technique in surface engineering.In order to revealthe reasons of excellent wear-resistance of the Ni-base FNiWC15 spray-welding coating , this paperinvestigated its microstructure,microhardness, distribution of alloy elements and wear- resistancethrough SEM observation,X-ray energy dispersive spectroscopy analysis and sliding wear test in drycondition . The results showed that its microstructure consists of dendrite matrix of Ni-base solidsolution+dispersive fine WC particles+polygonal compound particles with high Si and low Cr,W,Ni contents +compound particles with high Cr and low Si contents. The wear-resistance ofFNiWC15 spray-welding coating was 26 times that of 52100 steel.This research is of an importantmcaning for promoting the development of surface modification techniques and enlarging theapplication of spray- welding technique in industries.
