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.

石墨烯添加剂对 6063 铝合金 MAO 涂层微观结构和性能的影响

摘要微弧氧化工艺是通过在 6063 铝合金表面形成涂层来改善其性能的，为了进一步增强基础微弧氧化涂层的特性，在硅酸盐碱性电解液中加入了石墨烯。石墨烯的加入影响了所形成涂层的表面形态、厚度、元素分布、相组成、耐磨性和耐腐蚀性。研究采用了扫描电子显微镜、能量色散 X 射线光谱、X 射线衍射、X 射线光电子能谱、摩擦磨损测试和电化学工作站等手段。结果表明，涂层的微观结构和性能随着石墨烯浓度的增加而改变。然而，当石墨烯添加过多时，涂层的性能会变差。
