Abstract

Abstract

Ni-TiC boned diamond composites are fabricated by self-propagation high temperature sintering(SHS)from Ni/TiC/graphite/diamond powders.Effect of diamond size and content on the microstructure and phase composition of obtained samples is studied.The results show that the main phases of the products are Ni,TiC and diamond by SHS.When mole ratio of Ti and C is 1:1in the raw materials,it is difficult to obtain good coating on the surface of diamond by adjusting diamond content and size.Good coating can only be obtained when diamond size is finer(20 μm).Appropriate increasing Ti content in the raw materials may form uniform Ni-TiC complex coating on the surface of diamond.The size of TiC grains are about 1 μm.
