Study on Preparation of WC-6Co Cemented Carbide by High Temperature and High Pressure Sintering and its Mechanical Properties AITranslate
Abstract AITranslate
Using the composite powder with an average particle size of about 300 nm as raw material, WC-6 Co cemented carbide was prepared by high temperature and high pressure sintering at different temperature for different time.The influence of preparation process on the crystal structure, microstructure and mechanical properties of WC-6 Co cemented carbide was studied by X-ray diffractometer, optical microscope and microhardness tester.The results show that the fluidity of liquid Co, rearrangement of WC particles and grain size of the sample during sintering play an important role in the density, Vickers hardness and fracture toughness of the alloy.Comprehensively considering the properties of the alloy, the optimized high temperature and high pressure sintering process conditions are 6 GPa pressure, 1 400 ℃ temperature and 15 min holding time.The microstructure of the alloy prepared by the above sintering process is uniform and fine, the Vickers hardness reaches 2 100 HV10,and the fracture toughness reaches 16.81 MPa·m1/2,which are better than those of WC-6 Co cemented carbides prepared by SPS and hot-pressing sintering.
