Abstract
Abstract The micro-arc oxidation process is used to improve the properties of 6063 aluminum alloy by forming coatings on the surface of the alloy, in order to further enhance the features of the basic micro-arc oxidation coatings, graphene was added into the silicate alkaline electrolyte. The addition of the graphene influences the surface morphologies, thickness, element distributions, phase compositions, wear resistance and corrosion resistance of the formed coatings. They were studied by means of scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, friction and wear testing and an electrochemical workstation. The results show that the microstructure and properties of the coating were modified with the increase of graphene concentration. However, when too much graphene was added, the performance of the coating became worse.
