Results are provided for a study of the anodic behavior of aluminum alloy AK7 and composite material of the Al–Al₂O₃ (Oxidal) system in an electrolyte medium of 0.03, 0.3, and 3.0% NaCl. Corrosion-electrochemical study of alloys shows that with an increase in chloride ion concentration within electrolyte alloy corrosion rate increases by a factor of 1.3–1.7. It is shown that composite material of the Al–Al₂O₃ system has better corrosion resistance than the original AK7 alloy. At the same time, alloy pitting resistance also increases, as shown by the shift in pitting and corrosion potentials into a positive range of values.

AK7 铝合金和 Al-Al2O3 体系复合材料在 NaCl 电解质溶液介质中的阳极行为

研究结果用于研究铝合金 AK7 和 Al-Al ₂ O ₃（氧化）系统复合材料在 0.03、0.3 和 3.0% NaCl 电解质介质中的阳极行为。合金的腐蚀电化学研究表明，随着电解液中氯离子浓度的增加，合金腐蚀速率增加 1.3-1.7 倍。结果表明，Al-Al ₂ O ₃系复合材料比原始AK7合金具有更好的耐腐蚀性能。同时，合金的抗点蚀能力也增加，如点蚀和腐蚀电位向正值范围的转变所示。
