| 摘 要： | 为了改善GCr15轴承钢在脂润滑条件下的摩擦学性能,通过2种方法将FeS固体润滑材料应用于脂润滑下轴承钢材料的摩擦过程中.通过低温离子渗硫处理在轴承钢表面制取渗硫层;将FeS材料研磨成微米粉末添加到润滑脂中.在球-盘摩擦磨损试验机上对比研究了轴承钢渗硫层和使用FeS微米粉末的摩擦学性能.研究表明:在材料表面制取渗硫层和使用FeS粉末均可有效改善轴承钢在脂润滑条件下的减摩抗磨性能.在较低转速和载荷下,轴承钢表面渗硫层的摩擦磨损性能较使用FeS粉末更好,而在高速重载的工况下,轴承钢表面在使用FeS粉末时体现出更好的抗磨性能. |

| Abstract: | In order to improve the tribological property of AISI 52100 steel, FeS powders were used as an additive in lithium grease, and an iron sulfide layer on top of 52100 steel was prepared by using a low temperature ion sulfuration technology. The tribological properties of sulfide layer and FeS powders were investigated on a ball-on-disc friction and wear tester. It was found that the tribological properties of AISI 52100 steel under grease lubrication can be improved remarkably by using a sulfide layer on AISI 52100 steel and FeS powders as an additive in lithium grease. The tribological performance of the iron sulfide layer on AISI 52100 steel surface was better than that using FeS powders at low load and speed. 52100 steel possessed better anti-wear property under more harsh conditions using FeS powders as an additive. |
