SiC-coated hexagonal boron nitride composite powder modified self-lubricating ceramic cutter material and preparation method thereof

XU CHONGHAI / CHEN HUI / CHEN ZHAOQIANG / YI MINGDONG / XIAO GUANGCHUN / MA JUN

The invention relates to a SiC-coated hexagonal boron nitride composite powder modified self-lubricating ceramic cutter material and a preparation method thereof. The ceramic cutter material is prepared from the following raw materials in percentage by volume: 20-80% of aluminum oxide, 10-80% of titanium carbide, 1-20% of SiC-coated hexagonal boron nitride composite powder and 0.2-5% of magnesium oxide serving as a sintering aid. The invention further provides the preparation method of the ceramic cutter material; since the surface of hexagonal boron nitride composite powder is coated with SiC, the mechanical property of the material can be enhanced and the wettability of h-BN and a substrate can be improved and therefore agglomeration can be reduced.
