Study on Synthesis and Properties of CBN-WC-Co Superhard Tool Materials AITranslate
Abstract AITranslate
Using cubic boron nitride(CBN),tungsten carbide and cobalt powder as experimental raw mate-rials, after high temperature vacuum treatment, PCBN composites with different WC-Co contents were synthesized by high temperature and ultra-high pressure sintering on a six-sided top press.The phase, compactness, hardness, abrasion ratio, impact toughness and micro morphology of the PCBN composites were analyzed.The results show that in the experimental range, when the WC-Co content is 11%,the bonding force between CBN and the binder is weak, the internal structure of the PCBN composite is relatively loose, the porosity of the sample is the highest, and the wear ratio and microhardness reach the maximum, 7 200 and 35.6 GPa, respectively.When the WC-Co content is 20%,the porosity on the surface of the PCBN composite is significantly reduced, the internal structure is compact, the porosity is the lowest, the density is significantly improved, and the flexural strength and impact times reach the maximum, 750 MPa and 80 times, which are 22% and 45% higher than those of the PCBN composite with 11% WC-Co content, respectively.
