Therefore, in order to study the mechanism of the formation of sintered diamond and some of its properties, it is important to investigate the forms and characteristics of the additives in it. In this paper a research into the sintering of polycrystalline diamond under ultrahigh pressure with nickel as an additive is briefly reported.展开更多
