| 目的 采用盐雾对比试验，优选获得抗腐蚀性能优异的防护体系。方法 选用飞机常用的两种结构材料（2024、30CrMnSiA）的几种备选防护体系，开展盐雾加速腐蚀试验。结果 铝合金试件经过10个周期盐雾加速腐蚀试验，涂层鼓泡失效，基体未发生腐蚀；经过7个周期加速腐蚀试验，结构钢试件预制划痕处涂层剥落、基体腐蚀。结论 铝合金外部防护体系B方案（铬酸阳极化+ 37底漆+ E面漆）和内部防护体系H方案（铬酸阳极化+ TB06底漆）最佳，结构钢推荐选用GE方案（镀镉+钝化+TB06底漆+TS96面漆）。 |

| Objective To select a protection system of good corrosion resistance through salt spraycomparisontest. Methods Several alternative protection systems with two structural materials (2024, 30CrMnSiA) commonly used in aircraft were selected to carry out salt spray accelerated corrosion test. Results After 10 cycles of test, the coatings of Al alloy specimens bubbled and failed, but the substrate remained uncorroded; after 7 cycles of test, the coatings of structural steel specimens flaked and failed, and the substrate was corroded in the prefabricated scratches. Conclusion Al alloy external protection system—scheme B (chromate anodizing + 37 primer + E finish) and the internal protection system—scheme H (chromate anodizing + TB06 primer) outperform the other schemes. It is recommended to apply scheme GE (cadmium plating + passivation + TB06 primer + TS96 finish) for structural steel. |
