近年来Si3N4基陶瓷刀具在铸铁的切削加工中已得到较为成功的应用.但在加工碳钢等材料时，却产生较严重的化学磨损.不仅如此，干切削条件下陶瓷刀具和金属工件接触区产生的高温加剧了刀具与工件接触面间元素相互扩散，Si3N4颗粒的氧化及其氧化产物Si3O2的熔融，会大大加剧陶瓷材料的粘着磨损和微断裂磨.本试验采用润滑剂的润滑、冷却作用，尤其极压抗磨添加剂的摩擦化学作用来减小陶瓷的磨损率.在销-盘试验机上考察了ZDDP和TCP两种常用抗磨添加剂的性能.结果表明，两种添加剂均具有很好的减摩抗磨效果.分析认为，摩擦过程中添加剂发生了摩擦化学反应，其摩擦化学反应产物起到了很好的边界润滑作用，减小了摩擦系数和磨损率.
In recent years, Si3N4-based ceramic cutting tools in the cast iron has been more successful in the application, but in the processing of carbon steel and other materials, but have more serious chemical wear and tear.In addition, dry cutting conditions, ceramic cutting tools and metal workpiece contact area The high temperature exacerbated by the tool and the workpiece contact surface elements interdiffusion, Si3N4 particles oxidation and oxidation of Si3O2 melting, will greatly aggravate the adhesion of ceramic materials wear and micro-fracture mill.This test uses lubricant lubrication, cooling effect , Especially the friction and chemical action of extreme pressure antiwear additives to reduce the wear rate of ceramic.The performance of two commonly used antiwear additives ZDDP and TCP was investigated on a pin-plate testing machine.The results showed that both additives have very good The results show that the friction chemical reaction occurs during the friction process, and the tribochemical reaction product has a good boundary lubrication effect, reducing the friction coefficient and wear rate.
