Abstract

The influence of the parameters of the plasma-electrolytic oxidation process of WE43 magnesium alloy in a pyrophosphate electrolyte on the structure, composition, and protective properties of the formed coatings was studied using scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray phase analysis, and electrochemical methods. It has been shown that, with an increase in the duration of plasma electrolytic oxidation, the porosity of the formed coatings decreases and the content of magnesium orthophosphate in their composition increases. It was found that, compared to the original sample of WE43 alloy, PEO helps to reduce the corrosion rate in Hanks solution by 4.1–31.6 times.

等离子体电解氧化参数对稀土WE43镁合金成分、组织和表面性能的影响

采用扫描电镜、能量色散x射线能谱、x射线物相分析和电化学等方法研究了WE43镁合金在焦磷酸盐电解液中等离子体电解氧化过程参数对镀层结构、组成和防护性能的影响。结果表明，随着等离子体电解氧化时间的延长，形成的涂层孔隙率降低，其成分中正磷酸镁的含量增加。研究发现，与WE43合金原始样品相比，PEO有助于将汉克斯溶液中的腐蚀速率降低4.1-31.6倍。
