Abstract The abrasive wear resistance of laser clad ceramic-metal composite coatings composed of different kinds, size and weight percent of WC particles has been investigated systematically, in which the single crystal WC, cast WC and cemented WC particles are used as the ceramic phases and Ni-base self-flux alloy as the matrix. The experimental results show that the abrasive wear resistance of the composite coatings is determined by the kinds, sizes, weight fractions of WC particles, and the changing tendency of the abrasive wear resist-ance of the weight fraction of the coatings depends on the type of WC particles.
