半金属摩擦材料与金属对偶的摩擦起源于接触区附近的表面形变和粘着。各种固体润滑剂材料可在摩擦表面上生成牢固的、分子定向的转移膜 ,使摩擦表面的摩擦变为固体润滑剂之间的摩擦 ,从而降低其摩擦与磨损。研究表明 ,不同的固体润滑剂润滑效率不同 ,改性效果对温度的依赖主要与固体润滑剂本身的温度特性有关 ;当少量填充固体润滑剂时 ,对磨耗即有明显改善 ,而摩擦系数下降不大 ,但用量过多会使摩擦材料的摩擦系数下降过低 ,同时磨耗性能的改善也会下降 ;几种固体润滑剂复合使用会提高固体润滑剂改性效率
Friction of the semi-metallic friction material to the metal pair originates from the surface deformation and adhesion near the contact area. A variety of solid lubricant materials can produce a strong, molecularly oriented transfer film on a rubbed surface that changes the rubbing of the rubbing surface to that of the solid lubricant thereby reducing its friction and wear. The results show that different solid lubricants have different lubrication efficiencies, and the dependence of temperature on the modification effect is mainly related to the temperature characteristics of the solid lubricant itself. When a small amount of solid lubricant is filled, the wear is significantly improved, while the friction coefficient decreases not Large, but the amount of too much friction coefficient of friction material will drop too low, while the improvement of wear performance will decline; several solid lubricant compound will improve the efficiency of solid lubricant modification
