  • In order to determine the selection principle of some mine cemented carbides, the performance differences of cemented carbides with the same hardness, different high cobalt content and low cobalt content were analyzed. YG8 T low cobalt coarse particles and YG18 T high cobalt fine particles cemented carbides with hardness of about 89.5 HRA were prepared. The properties of the two alloys were analyzed by metallographic examination and mechanical properties test. The fracture toughness and wear resistance of the two alloys were tested. The results show that the wear resistance of low cobalt coarse particle cemented carbides with the same hardness was better, and the high cobalt fine particle cemented carbides had better fracture resistance.
