摘要	Using laser cladding technique, Ni3(Si, Ti) matrix composite coatings reinforced by WC and in-situ synthesis TiC multi-ceramics were fabricated by preplacing Ni78Si13Ti9(at%) powders containing three different WC contents on the nickel-matrix superalloy substrate. By means of SEM, EDS and XRD, microstructures of the coatings were investigated, and micro-hardness were measured. The results showed that excellent metallurgical bonding between the coatings and the substrates was obtained. Phases of the coatings are mainly composed of gamma Ni(Si) solid solution, Ni3(Si, Ti), WC-TiC multi-ceramics. With increasing WC percentage, content of carbides formed in the coatings increases, but porosity is also enhanced. The main morphologies of ceramics evolve from irregular polygonal shape to petal like shape, then irregular polygonal shape coexisting with petal like shape.
