The mechanisms of wear

Wear is rarely catastrophic, but it reduces operating efficiency and increases power losses, oil consumption,and component replacement rates. Wear is not an intrinsic material property, but a characteristic of the engineering system. Any change in load, speed, or environment. for example, can cause a dramatic change in the wear rates of one or both of the contacting surfaces1. TE 99 通用摩擦磨损试验机
