查询词典 abrade wear

With the automatization of degree have improved in the industry, the demand of the mechanism continuity and security also have increased, the reason that cause the operation of mechanism to invalidation is the wear by the friction, which abrade the movement component and joint component.

随着工业自动化程度的提高，对机械零件工作的连续性、安全性要求也提高，而实践证明，导致机械运转失效的主要原因是由于活动构件或者联结件在摩擦力的作用下产生的磨损，磨损导致机械的运转失效，更可能引发安全隐患，这其中磨料磨损占整个磨损总量的50％，故越来越多的研究者对抗磨料磨损的材料进行了一系列的研究。
