研究了Ｓｉ３Ｎ４陶瓷与ＳＵＳ３０４不锈钢摩擦性能，认为反应烧结氮化硅的微观结构有利于储存润滑介质．同时发现水基润滑剂具有较好的润滑效果，主要原因是摩擦化学反应层的存在使摩擦系数降低．在研究基础上，将氮化硅陶瓷用作金属塑性成形模具材料．实验证明，反应烧结氮化硅陶瓷制造模具可成功用于不锈钢的拉深． The tribological properties of Si3N4 ceramics and SUS304 stainless steel were studied. It is considered that the microstructure of reactively sintered silicon nitride is good for the storage of lubricating media. At the same time, it is found that the water-based lubricant has a good lubricating effect, mainly due to the friction coefficient reduced by the existence of the tribochemical reaction layer. Based on the research, silicon nitride ceramics are used as metal plastic forming mold material. Experiments show that the reactive sintering of silicon nitride ceramic mold manufacturing can be successfully used for drawing stainless steel.
