| 目的 获得有效的耐舰载机酸性盐雾典型环境腐蚀性能的2A12铝合金表面处理方法。方法 分别利用铬酸阳极氧化、硫酸阳极氧化、苹果酸阳极氧化等方法对2A12铝合金表面进行处理，并采用3种不同类型的漆进行涂漆防护，然后按照GJB 150.11A—2009进行酸性盐雾试验考核。结果 铬酸阳极氧化和其中2种防护漆体系不耐酸性盐雾腐蚀，硫酸阳极氧化和苹果酸阳极氧化耐酸性盐雾腐蚀性能好，丙烯酸聚氨酯/氟聚氨酯涂层体系耐酸性盐雾腐蚀性能良好。结论 硫酸阳极处理并喷涂丙烯酸聚氨酯/氟聚氨酯涂层可有效提高2A12铝合金的耐腐蚀性。 |
| 英文摘要: |
| The work aims to identify effective surface treatment methods for the 2A12 aluminum alloy to enhance its corrosion resistance in typical corrosive environments such as acidic salt spray. Surface treatments including chromic acid anodizing, sulfuric acid anodizing, and malic acid anodizing were applied to the 2A12 aluminum alloy, followed by application of three different types of coatings for corrosion protection. Evaluation was conducted according to GJB150.11A-2009 standard through acid salt spray tests. Chromic acid anodizing and two of the coating systems did not withstand acid salt spray corrosion. Sulfuric acid anodizing and tartaric acid anodizing exhibited good resistance to acid salt spray corrosion, especially with acrylic polyurethane/fluoropolyurethane coating systems showing excellent performance. Sulfuric acid anodizing followed by application of acrylic polyurethane/fluoropolyurethane coatings effectively enhances the corrosion resistance of 2A12 aluminum alloy. |
