中文摘要:
      针对某型铸铝合金的不同热处理状态、 不同厚度的微弧氧化膜的防腐蚀性能进行了960 h的盐雾对比试验。结果表明, 对于该型铸铝合金T7热处理状态防腐蚀能力优于T5; 微弧氧化处理能明显提高该型铸铝合金防腐蚀能力, 经不同厚度微弧氧化处理的该型铸铝合金, 腐蚀深度无显著差异; 在相同面积区域内, 腐蚀损伤的程度有明显的不同, 50~70 μm的微弧氧化膜防腐蚀性能最好。
英文摘要:
      960 hours of salt spray test were carried out on cast aluminum alloy specimen with different heat treatment and different thickness of micro-arc oxidation film. The result showed that the anti-corrosion performance of T7 is better than that of T5, and the micro-arc oxidation film improved corrosion resistance of cast aluminum alloy obviously. The corrosion depth of different thickness of micro-arc oxidation film has no difference, but the corrosion damage degree has obvious difference in the same area. The anti-corrosion performance of micro-arc oxidation film thickness of 50~70 μm is the best.
