为了改善轴承钢渗硫层在油润滑条件下的摩擦学性能,将FeS粉末作为添加剂添加到润滑油中使用,在球-盘摩擦磨损试验机上考察了FeS微粒与表面硫化层的复合作用。研究表明:渗硫盘与润滑油中的FeS微粒可以取得很好的复合效果。在磨损过程中FeS微粒可以不断被吸附到表面从而有效地补充渗硫层的损失,增强了渗硫层在较苛刻工况下抵抗磨损的能力。在合适的添加浓度下,使用粒度较小的FeS复合作用更为明显。

In order to improve the tribological properties of the bearing steel infiltrated layer under the conditions of oil lubrication, the FeS powder was added to the lubricating oil as an additive, and the composite effect of the FeS particles and the surface vulcanized layer was investigated on a ball-disc friction and wear tester. The research shows that the composite effect of FeS particles in the infiltrated disc and lubricating oil can be achieved. The wear of FeS particles can be constantly adsorbed to the surface to effectively replenish the loss of percolation layer and enhance the ability of the percolation layer to resist wear under harsh conditions. At the appropriate concentration, FeS composite with smaller particle size is more obvious.
