Abstract

Investigation of the structure formation during sintering PCD in HPHT condition with addition to diamond powder Ti or Si for activating sintering using SEM, EDX, XRD methods were made. The addition of Ti leads to formation of TiC, the addition of Si leads to formation of Co₂Si. Thus using such additions helps to decrease Co amount in the upper diamond layer and increase PCD wear-resistance
