本文研究了MoS_2和PTFE填充尼龙的耐磨时间与速度、负荷的关系,并将这些结果与纯聚合物的结果作了比较。 填有这些固体润滑剂的聚合物与金属表面摩擦时,可产生磨料磨损、粘着磨损和以膜转移为主的不同的磨损阶段,从而达到相当稳定的稳态磨损,其摩擦、磨损在很长的周期内保持低而稳定,这就是有用的工作期。在这稳态的滑动阶段,多数热塑性聚合物轴承的温度、摩擦和磨损往往遵循一个总的趋势——成为滑动速度或轴承负荷的函数,这部分地归因于聚合物的粘弹性。 利用摩擦学的这种性能,还可以测定聚合物在实际稳态时压力和速度的极限。填充固体润滑剂的聚合物比它们的纯聚合物表现出有较高压力和速度的承受能力。
In this paper, we studied the relationship between wear rate, load and speed of wear-resistant MoS 2 and PTFE filled nylon, and compared these results with those of pure polymer. Friction between the polymer filled with these solid lubricants and the metal surface can result in abrasive wear, adhesive wear, and different wear stages dominated by film transfer, resulting in fairly stable steady state wear with very long friction and wear The cycle remains low and stable, which is a useful working period. In this steady state sliding stage, the temperature, friction and wear of most thermoplastic polymer bearings tend to follow one general trend - becoming a function of sliding speed or bearing load, due in part to the viscoelasticity of the polymer. Using the tribological properties, it is also possible to determine the limits of the pressure and the velocity of the polymer at the actual steady state. Polymers filled with solid lubricants exhibit higher pressures and speeds than their neat polymers.
