| 摘 要： | 本文中采用多弧离子镀TiN薄膜对钢基体进行表面改性与SiCH润滑油相结合的方式,研究了SiCH油/TiN薄膜复合体系的真空摩擦学性能,并分析了该复合润滑体系的摩擦磨损机理.研究表明:在SiCH油/TiN薄膜复合体系中,摩擦副对偶双方表面均采用TiN薄膜进行改性后,由于TiN薄膜具有良好的稳定性和耐磨性,与SiCH润滑油构成的复合润滑体系在长寿命摩擦试验中表现出良好的减摩抗磨性能,平均摩擦系数约0.07,在经过1.8×10~6r的摩擦试验后,尽管SiCH油中形成了微量的多甲基基团的硅碳化合物Si-[R-(CH_3)_3]_3并未影响其良好的润滑性能,表明SiCH油/TiN薄膜复合体系耐磨寿命高达1.8×10~6r以上.

| Abstract: | The tribological properties of SiCH oil/TiN film composite system, which was prepared by multi-arc ion plating TiN film on substrate surface and SiCH lubrication oil combining technology, were studied by using a ball-ondisk tribometer. The wear mechanism was also discussed. The results show that SiCH oil maintained good frictionreducing and anti-wear properties for the friction pairs with both the disk and ball surfaces coated with TiN film. The good tribological properties were due to the good chemical stability and abrasive resistance. After 1.8×106 cycles friction test, the partial decomposition of the SiCH oil and presence of trace amounts of Si-[R-(CH3)3]3 in the process of vacuum sliding friction had no distinct effect on the lubricity of the SiCH oil. The wear lifetime the SiCH oil/TiN film composite system was longer than 1.8×106 cycles. |
