摘　　要：分别采用多弧离子镀技术及阳极氧化技术在LF6防锈铝基体表面制备了Ti(C,N)/TiN/Ti(C,N)/TiN/Ti(C,N)/TiN六层多元多层膜及阳极氧化膜,并对比考察研究了该两种膜的力学性能和摩擦学性能,结果表明:多元多层膜与阳极氧化膜划痕临界荷载分别为76N,60N;显微硬度分别为HV0.251404,HV0.25520;二者摩擦系数都较高,分别为0.66,0.76;都使对偶件磨损;但与传统的阳极氧化膜相比,多元多层膜硬度与耐磨性都提高了近2倍,且其摩擦曲线平滑,呈稳定磨损状态,而阳极氧化膜摩擦曲线呈跳跃状,呈非稳定磨损状态。Ti(C,N)/TiN/Ti(C,N)/TiN/Ti(C,N)/TiN six-layer multi-element-layer film and anodic oxide film were prepared on LF6 substrate by multi-arc ion plating and anodic oxide respectively. Their Mechanical and tribological properties were investigated. The results show that their critical loads are 76N and 60N respectively, microhardnesses are HV0.251404 and HV0.25520 respectively, and their friction coefficients are 0.66 and 0.76 respectively which are relatively high and result in wear of counter object. But both hardness and wear resistance of multi-element-layer film increase by 3 times compared with that of anodic oxide film. Furthermore, friction coefficient curve of multi-element-layer film presents smooth, which shows that the film is worn steadily, but that of anodic oxide film presents jumping, which shows worn of the oxide film is not steadily.
