摘要
本文采用双重处理表面改性技术对LY12CZ铝合金进行了摩擦学表面改性处理,即首先对LY12CZ铝合金进行硫酸阳极氧化处理,然后在其表面再沉积一层润滑薄膜。实验结果表明,双重处理可有效地降低铝合金在真空环境中的摩擦并且明显提高耐磨寿命。特别是采用低摩擦系数的MoS2-Au基复合薄膜,可在较高载荷下达到较长的耐磨寿命。对双重处理铝合金的摩擦失效机理也作了初步探讨。
In this paper, 2024 Al was doubly treated for tribological modification i.e. anodically oxidized firstly and then coated with MoS2 -Au composite film and Ti/Ag dual layer film by rf- spattering and multi - are ion - plating, respectively. The results showed that duplex treatment, especially spattered MoS2 - Au composite film, can decrease the friction coefficient and improve the endurance life of 2024 Al in vacuum. The lubrication failure mechanism of the duplex treated 2024 Al was also studied.
