摘要
文章全面阐述了部分稳定二氧化锆陶瓷（略作ＰＳＺ）以软金属或软金属氧化物润滑时的摩擦和磨损性能。ＰＳＺ在无润滑时的磨损率随负荷而增加，当负荷超过２０Ｎ时要发生从轻微磨损到严重磨损的转变。Ⅷ─ⅡＢ族软金属及其氧化物可以有效地防止ＰＳＺ的严重磨损，即使负荷达到３５．６Ｎ，磨损率仍保持为零，同时可以将ＰＳＺ的摩擦系数从０．４０减少到０．２０以下．
The friction and wear properties of partially stabilized zirconia(PSZ) lubricated with soft metal or oxide of soft metal are studied. The wear rate of unlubricated PSZ increase with normal loads. When loads are over 20 N, a transition from mild to severe wear occurrs. Ⅷ──Ⅱ B Soft metal and its oxide effectively prevent PSZ from severe wear. Even at a load of 35. 6 N the wear rate is essentially zero. The friction coefficients of PSZ are reduced from 0. 40 to that lower than 0. 20 for soft metal and its oxide.
