考察了Ｓｉ３Ｎ４基和Ｔｉ（ＣＮ）基两种陶瓷刀具切削１Ｃｒ１８Ｎｉ９Ｔｉ不锈钢的耐磨性能，对磨损表面进行了观察和分析，结果表明：ＦＤ０３在进刀量为０．１ｍｍ时，磨损值随切速变化比较稳定，在切速１．６ｍ／ｓ时出现最小磨损。进刀量为０．４ｍｍ时，磨损值出现跳跃，ＦＤ０３的主要磨损机制为微崩和粘着剥落；ＦＤ２２在两种进刀量条件下，出现了最佳切削速度（２．２ｍ／ｓ），其主要磨损机制是高温引起的陶瓷粘结剂的熔化导致粘着剥落。
The wear resistance of 1Cr18Ni9Ti stainless steel cut by Si3N4-based and Ti (CN) -based ceramic tools was investigated. The wear surface was observed and analyzed. The results show that the wear value of FD03 with the cutting feed rate of 0.1mm decreases with the cutting speed Change is relatively stable, the minimum wear occurs at a shear rate of 1.6m / s. When the feed rate is 0.4mm, the wear value jumps. The main wear mechanism of FD03 is micro-collapse and sticking. The optimum cutting speed (2.2m / s) The main wear mechanism is the melting of the ceramic binder caused by high temperatures leading to sticking and peeling.
