    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.
