几种类型的涂层，旨在提高铝合金在海水中的耐腐蚀性，进行了检查。在铝合金3003表面涂覆厚度约为30 μm的涂层，并通过刀口创建人工缺陷后，在70°C和pH 1.5的3%NaCl溶液中进行腐蚀试验。测试结果表明，氟树脂和溶胶-凝胶涂层都具有优异的阻隔能力。氟树脂涂层具有自修复能力，并且通过添加金属粉末来改善。
Several types of coatings, designed to improve the resistance of aluminum alloys to corrosion in seawater, were examined. A coating with a thickness of approximately 30 μm was applied to the surface of aluminum alloy 3003, and after creating an artificial defect by means of a knife‐edge, a corrosion test was carried out in 3% NaCl solution at a temperature of 70°C and pH 1.5. The test results showed that a fluorine resin and sol‐gel coatings both had excellent barrier abilities. The fluorine resin coating had self‐healing abilities, and this was improved by the addition of a metal powder.
