用硅酸盐-磷酸盐的复合溶液体系对6063铝合金进行微弧氧化，获得颜色均匀的黑色陶瓷膜。研究了添加剂（C6H12N4）对膜层的表面形貌、成分、组织结构、黑度、附着力、粗糙度和耐蚀性的影响。结果表明，添加剂使微弧氧化膜层黑度增加，膜层均匀性和附着力显著提高，粗糙度降低，但膜层的相组成不变，均为γ-Al2O3和A186V14。含添加剂的体系获得的微弧氧化膜层在3．5％NaCl溶液中的腐蚀电流密度相比无添加剂的体系获得的黑色膜层有很大程度的降低。
Black ceramic coating was obtained by micro-arc oxidation on 6063 aluminum alloy in an electrolyte containing silicate-phosphate. SEM, EDS, XRD, spectrophotometer, 3D morphology instrument were used to characterize the morphology, composition, microstructure, blackness, surface roughness and corrosion resistance of the ceramic coating. The results showed that the additive not only improved the blackness, homogeneity and adhesion strength of ceramic coating, but also reduced the surface roughness. The constituent phase in coatings from electrolyte with or without additive were the same, i.e. γ-Al2O3 and Als6V14. The corrosion current density of coating treated in electrolyte containing additive was much lower than that of the coating fabricated without additive, indicating significantly improved corrosion resistance.
