    摘要:

    用全封閉非平衡磁控濺射技術(shù)制備Graphit—ic和Dymon—ic薄膜。利用SEM，AFM，TEM，XRD，納米壓痕儀，高溫摩擦磨損試驗(yàn)機(jī)等研究了薄膜的微觀結(jié)構(gòu)、表面形貌、顯微硬度以及摩擦磨損性能。結(jié)果表明：Graphit—ic薄膜和Dymon—ic薄膜均由非晶組織構(gòu)成，薄膜均勻、致密，粗糙度小：Graphit—ic薄膜的顯微硬度低于Dymon—ic薄膜；同時(shí)，在干摩擦條件下，Graphit—ic薄膜和Dymon—ic薄膜與GCr15鋼球?qū)δr(shí)顯示出良好的耐磨減摩性能，Graphit—ic薄膜的摩擦系數(shù)低于Dymon—ic薄膜，但其比磨損率卻高于Dymon—ic薄膜。

    Abstract:

    Graphit-ic and Dymon-ic coatings were deposited by closed field unbalanced magnetron ion plating. The microstructure, morphology, microhardness and tribological properties of the coatings were investigated by means of scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), transmission electron microscopy (TEM), nano-indentation, friction and wear testing. The results show that Graphit-ic and Dymon-ic coatings are dense and smooth. The structure of two coatings is all amorphous. The microhardness of Graphit-ic is lower than Dymon-ic coating. They show a good friction-reducing and a antiwear behavior in sliding against GCr-5 steel. The friction coefficient of Graphit-ic is lower than Dymon-ic, hence, the wear rate of Graphit-ic is higher than Dymon-ic.
