本文采用射频溅射技术制备了MoS2薄膜,用UMT-2MT摩擦试验机考察了MoS2膜/钢球摩擦副分别在干摩擦、氟丙基氯苯基硅油(115#油)和KK-5脂(由115#润滑油经聚四氟乙烯粉稠化制成)润滑条件下的摩擦学性能,并分析了其润滑和失效机制.结果表明:脂润滑状态下,MoS2+KK-5复合膜处于不连续的边界润滑,其摩擦学性能得到改善但不明显;115#油润滑条件下,由于连续、有效的边界润滑,使得MoS2+115#固体-油复合体系的摩擦系数低而平稳,其耐磨损寿命与单独MoS2薄膜相比提高了至少8倍;相对于上述2种情况,干摩擦条件下的MoS2膜磨损明显.
In this paper, MoS2 thin films were prepared by radio frequency sputtering technology. The effects of dry friction, fluoropropyl chlorophenyl silicone oil (115 # oil) and KK-5 grease The tribological properties of Lubricating Oil from 115 # lubricating oil were studied by means of polytetrafluoroethylene powder thickening. The lubrication and failure mechanism were analyzed. The results show that the MoS2 + KK-5 composite membrane The frictional properties of MoS2 + 115 # solid-oil composite system are low and stable due to the continuous and effective boundary lubrication under the condition of oil lubrication of 115 # The wear life is at least 8 times higher than that of the MoS2 film alone. Compared with the above two cases, MoS2 film wear under dry friction is obvious.
