Research on Preparation Process of Graded Cemented Carbide by One-step Sintering AITranslate
Abstract AITranslate
Considering the cost, graded cemented carbide was prepared by one-step sintering in a vacuum furnace. The influence of sintering technological parameters on microstructure and density was studied. The results indicate that WC grains in alloy surface layer are larger than those in Co-rich layer and core region. As sintering temperature increases,WC grains in alloy surface layer become coarse,and density of the alloy increases at first and then decreases. Longer sintering time results in significantly increased thickness of two-phase area in alloy surface layer. The thickness of the graded layer of the prepared cemented carbide in the experiment can reach 1 168μm,and alloy density decreases with longer sintering time.
