摘　　要：通过工艺实验研究,分析了等离子清洗对航空典型铝合金材料硫酸阳极氧化膜层耐蚀性的影响,对等离子清洗后的阳极氧化膜层进行中性盐雾试验。结果表明,该清洗方式不会降低铝合金阳极氧化膜层的耐蚀性能,确保了工件氧化膜层防护的可靠性。In this paper, the influences of plasma cleaning technology on corrosion resistance of sulfuric acid anodizing film on typical aluminum alloy in aviation industry were analyzed by process test researching, and neutral salt spray test was done for the anodizing film after the plasma cleaning. Results showed that this cleaning method wouldni reduce the corrosion resistance of the anodizing film, and protective reliability of the anodizing film on work-piece could be ensured.
