Research Abstract

Polycrystalline Diamonds (PCDs) are generally prepared by sintering at ultra-high pressure about several GPa because of low sinterability and transformation to graphite at high temperatures. This research aimed to prepare dense Diamond-based composites under moderate pressures (below 100 MPa) by Spark Plasma sintering (SPS) using nano-composite powders via a rotary chemical vapor deposition (CVD) technique.
SiC nano-layers were coated on Diamond powder by rotary CVD. The Diamond/SiC core/shell nano-structured powder was consolidated by SPS with SiO2 powder. The resultant Diamond-based composite with SiC and SiO2 exhibited the high relative density of 94% and the high Vichers hardness of 39 GPa.
