Reinforced wear-resistant Si3N4-BN-based composite ceramic cutter and preparation method thereof
The reinforced wear-resistant Si3N4-BN-based composite ceramic cutter is prepared from the following raw materials in percentage by weight: 20 to 22 weight percent of alpha-Si3N4, 11 to 13 weight percent of gamma-Si3N4, 16 to 17 weight percent of r-BN, 13 to 15 weight percent of c-BN, 10 to 12 weight percent of Ti (C, N), 8 to 10 weight percent of TiC, 2.0 to 2.5 weight percent of Co, 3.0 to 3.5 weight percent of Ti, 2.0 to 2.5 weight percent of Mo, 1.5 to 2.0 weight percent of sintering agent, 3.0 to 4.0 weight percent of dispersing agent, 0.8 to 1.0 weight percent of lubricating agent, 0.5 to 1.5 weight percent of reinforcing agent, 1.3 to 2.5 weight percent of coating material and 2.0 to 2.5 weight percent of negative ion powder. According to the invention, Si3N4 and BN are used as main body base materials of the ceramic cutter, and the compactness, the sinterability and the like of the cutter are improved by optimizing the formula design and the preparation process, so that the quality and the performance of the composite ceramic cutter are remarkably improved, and the high-precision turning requirement can be well met.
