Analysis on Microstructure of Graphite-like Composite Coating on Metal Substrate
The graphite-like composite coating was deposited by closed field unbalanced magnetron sputter iron plating technique.The surface and fracture morphology of the coating were observed by SEM and AFM,the cross-sectional structure was analyzed using TEM.The tribological properties curve of the coating was also tested.The results indicate that the graphite-like composite coating is made up of colummnar polycrystalline chromic metallic transition layer,amorphous gradient layer and graphite-like composite coating.
