| 中文摘要: |
| 目的 评价新型航空清洗剂对航空铝合金防盐雾性能的影响。方法 对航空铝合金7075在施加清洗剂清洗后开展中性盐雾试验，通过扫描电子显微镜、能谱分析仪、高分辨率拉曼光谱等研究手段，对铝合金的表面形貌、组织成分及关键化学组分的变化情况进行对比分析，综合评价该清洗剂对铝合金的性能影响。结果 经过新型航空清洗剂清洗和6 h中性盐雾试验后，清洗剂仍在铝合金表面残留有保护膜，且清洗后的铝合金表面经盐雾实验后依然光亮，有明显的二次相颗粒，无絮状物和氯化钠结晶体，其表面褐色腐蚀斑点也更小。结论 经清洗后，铝合金的盐雾腐蚀程度明显更轻，说明清洗剂中的缓蚀剂成分起到了保护作用，该清洗剂具有防盐沉降的作用，可提升航空铝合金的防盐雾腐蚀性能。 |

| The work aims to evaluate the effect of new cleaning agent on anti-salt fog performance of aeronautical aluminum alloy. The neutral salt spray test was carried out on the aeronautical aluminum alloy 7075 cleaned with the cleaning agent. Then, the changes of surface morphology, microstructure and key chemical components of the aluminum alloy were studied by means of scanning electron microscope, energy spectrum analyzer and high resolution Raman spectrum and the effect of the cleaning agent on aluminum alloy was evaluated comprehensively. After cleaning with the cleaning agent and 6 h neutral salt spray test, the cleaning agent still left a protective film on the aluminum alloy surface, and after salt spray test, the cleaned aluminum alloy surface was smooth, had significant secondary phase particles, and had no significant brown spots or flocculent corrosion products. The degree of salt spray corrosion of aluminum alloy after cleaning is obviously lighter, which shows that the component of inhibitor in the cleaning agent plays a role of protection, and the new cleaning agent has the function of preventing salt deposition and can improve the anti-salt fog corrosion of aeronautical aluminum alloy. |
