چکیده انگلیسی
Hard carbide cermets are prepared by in-situ synthesis and infiltration of metal melts into WC powder compacts. Ni-W and Ni-W-Cr metal melts are in-situ synthesized from thermite reactions and infiltrated into WC powder compacts under high-gravity. During the infiltration, W in the metal melts reacts with WC to form W2C, and more W2C and W are observed at the upper parts of the cermets than the lower parts. The cermets show a maximum hardness of 15.4Â GPa, which is higher than most commercial cemented carbides, although they are not fully dense and have a porosity of 15-20%.
