The spark sintering technique was utilized to fabricate WC-16 mass%(Ni-P) compacts with different P contents using two starting powders, Ni plated WC particles by elctroless Ni plating solutions with different P contents and their elementally blended ones. The sintering temperature decreased as P content in Ni binders increased, and all compacts had theoretical densities (13.6-13.9 Mg/m³) under the optimum sintering conditions depending on binder-compositions. The sintered compacts consisted of WC, Ni and Ni₃P phases. Higher P containing alloy fabricated at lower temperature (1150 K), showed theoretical density, compared with that (1273 K) for lower P containing ones. Both uniform deformation of Ni+P binders and a large amount of Ni₃P with low melting point, resulted in excellent sinterability. It was found that noticeable grain growth of WC particles during the spark sintering was not observed and homogeneously sintered structure was obtained, due to pressure application at lower temperature and uniformly Ni plating on WC particles. The compacts produced from the electroless Ni plated WC particles showed higher and no-scatter values on hardness, compared with ones produced by elementally powder blending. The dynamic coefficient of friction showed the same value at initial state, but a little higher value at steady state in higher P containing alloys. Wear loss of alloys increased as Ni₃P contents increased in binder phase, because in addition to wear of WC particles, separation of WC particles was also caused from alloy-structure by failure of binder phases consisting of Ni and Ni₃P due to their brittleness under the wear conditions.
