We study the influence of electrolyte composition and the parameters of the plasma-electrolytic oxidation of D16Т alloy on the corrosion resistance of synthesized coatings in a 3% NaCl aqueous solution. It was discovered that oxide-ceramic coatings decrease the density of corrosion currents by an order of magnitude as compared with the initial alloy. The lowest corrosion currents were recorded in coatings synthesized for the ratios of the cathodic and anodic components of current j_c / j_a equal to 15/10 and 10/10. It is shown that corrosion currents become stronger as the content of hydrogen peroxide (H₂O₂) in the electrolyte increase. This is explained by the increase in the sizes of through pores in the synthesized coatings. Through these pores corrosive media penetrate to the base material and, as a result, the rate of aluminum dissolution becomes higher.

我们研究了D16Т合金的电解质组成和等离子电解氧化参数对3％NaCl水溶液中合成涂层耐蚀性的影响。已经发现，与初始合金相比，氧化物陶瓷涂层将腐蚀电流的密度降低了一个数量级。记录的最低腐蚀电流记录在合成的涂层中，电流j _c / j _a的阴极和阳极成分之比等于15/10和10/10。结果表明，随着过氧化氢（H ₂ O ₂）中的电解质增加。这可以通过合成涂层中通孔尺寸的增加来解释。腐蚀性介质通过这些孔渗入基材，结果，铝的溶解速度变高。
