| 摘 要： | 用四球摩擦磨损试验机考察了二烷基二硫代磷酸（DDP）修饰FeS纳米微粒作为润滑油添加剂的摩擦学行为.结果表明,DDP修饰FeS纳米微粒在极低的添加量时即具有良好的抗磨效果,但不能降低基础油的摩擦因数;磨损表面分析表明钢球表面形成了边界润滑膜,使摩擦学性能得到明显改善. |

| Abstract: | A four-ball machine was used to investigate the tribological behavior of DDP coated FeS nanoparticles as additive in liquid paraffin. As the results, DDP coated FeS nanoparticles as additive effectively increases the friction-reduction. The analytical results of SEM indicate that aboundary film is formed on the steel ball surface under the lubrication of liquid paraffin containing DDP-coated FeS nanoparticles. This contributes to improve the friction-reduction. |
| Keywords: | nanoparticles surface modification FeS tribological behavior |
