锌铝合金在油润滑条件下滑动摩擦特性的探讨

Research of Sliding Frictional Property of Zn-Al Alloys under Oil Lubricating Condiction

对两种锌铝合金 ZA—Si 和 HDZA 在20号机油润滑条件下的滑动摩擦特性进行了探讨。结果发现:该摩擦—润滑系统以边界润滑为主,且伴随断续、短暂的混合润滑或弹性流体润滑;摩擦磨损过程中犁削、辗压和粘着三个磨损机制在相互作用或共同作用;两种锌铝合金在一定的条件下具有优良的耐磨性能和减摩性能。

The Sliding Frictional Property of two kinds of Zinc-Aluminium alloys(ZA-Si and HDZA)under oil Lubricating condition have been studied in this thesis.It has been found that the frictional and lubricant system is mainly boundary lubrication with intermittent transient mix lubrication or elasto-hydrodynamis lubrication,the trietional wear is results that the wear mechanisms of plough cut,roller compaction and adhesion interchange or interact on each other,and ZA-Si alloy and HDZA alloy have excellent abrasion resistance and antifrictional property under certain conditions.
