The anodic film containing particles has a good wear-resistance and self-lubricating properties which is beneficial to oil-free industrial machinery applications. In the present study, incorporation of graphene in the matrix of the coating will be used to reduce defects and improved tribological properties of aluminium alloy. The microstructure and cross section of the films was studied by scanning electron microscopy. Micro-hardness measurement and ball on disc wear tests was performed to evaluate the mechanical and tribological properties of the composites, respectively. The results show the that the composite anodic film has less micopores and better mechanical properties than the film without graphene. This composite anodic film could be the attractive advanced material for wide range of mechanical application
