摘要: 研究了粉末冶金高速钢刀具经强化多元共渗后的磨损性能及切削特性。试验结果表明,经强化共渗的刀具切削力、摩擦系数降低,显微硬度和耐磨性提高,尤其在中速切削条件下,切削性能和耐磨性能改善更为显著。Abstract: This paper deals with the wear resistance and cutting characteristics of sintered high speed steel cutting tools with Co-impregnating layer. The experimental results show that its coefficients of friction and cutting force decreased obviously and surface hardness and wear resistance increased.Especially at a condition of intermediate cutting speed, the cutting ability and wear risistance are remarkably improved.
