摘要
Abstract
The pure wear experiment was performed on an M-2000 triboiogical tester, and the dry sliding friction and wear process of the oil impregnated QPQ surface was studied. It was found by the wear curve and friction coefficient curve that there was a metasta-ble stage during the transition from dry friction to boundary friction. In steady wear stage, the wear rate and the friction coefficient was only one third of the sampe without being oil impregnated. The wear mechanism was studied by analyzing the wear surface of each stage through SEM. It was found that in wear stage, the wear mechanism was adhesive wear; in metastable stage the wear mechanism was micro cutting; in stabilization stage, the wear mechanism was scuffing. The trial results showed that a certain degree of loose layer of QPQ surface can store oil, reducing friction coefficient so as to avoid or decrease adhesive wear and abrasive wear.关键词
