Effects of alloying elements on structure of plasma electrolytic oxidation ceramic coatings on aluminum alloys

摘要：

　　Alloying elements have vital effect on the formation of ceramic coatings.In order to research the effects of Cu,Mg,Si and Zn on plasma electrolytic oxidation (PEO) coatings,experiments of PEO were carried out on aluminum and its alloys in sodium silicate-sodium hydroxide solutions.Its microstructure and phase composition were analyzed by scanning electron microscope and X-ray diffraction.Results showed that,high content of Cu,Si and Zn in alloys suppressed process of some reactions,Mg element had different effects on high-temperature phase transformation of alumina ceramics while its weight percentage varied.
