为了减少机械零件的摩擦和磨损,常常推荐在矿油中,添加固体润滑剂。然而在流体润滑剂中通常还采用油溶性抗磨和极压添加剂。作者,采用三种不同的试验装置,模拟混合膜润滑的条件,研究了MoS_2与某些抗磨和极压添加剂的相互作用。研究结果指出,在多数情况下,MoS_2对抗磨性能起到了一定的正效应。在球—圆柱体装置上的研究表明,MoS_2提高了液体润滑剂的负荷承载能力。不过对于某些实际应用,仍需要细致地试验固体润滑剂的效果。
In order to reduce the friction and wear of mechanical parts, it is often recommended to add solid lubricant to mineral oil. However, oil-soluble anti-wear and extreme pressure additives are also commonly used in fluid lubricants. The authors used three different experimental devices to simulate the conditions of mixed film lubrication and to study the interaction of MoS 2 with certain antiwear and extreme pressure additives. The results show that, in most cases, MoS 2 has a positive effect on wear resistance. Research on ball-cylinder devices shows that MoS 2 increases the load carrying capacity of liquid lubricants. However, for some practical applications, it is still necessary to carefully test the effect of the solid lubricant.
