对2024-T3铝合金进行了阿洛丁1200S处理，通过盐雾试验研究了原料，前处理工艺，阿洛丁1200S处理时间、含量和pH，以及后处理等工艺环节对2024-T3铝合金耐盐雾腐蚀性能的影响。结果表明：在阿洛丁1200S处理工艺的前处理阶段，碱清洗效果要保证铝合金表面水膜连续，脱氧时间为1~3 min；阿洛丁1200S含量最佳控制范围为11.3~12.5 g/L，最佳pH范围为1.6~1.8；阿洛丁1200S处理后的水清洗不得使用喷淋装置；同时干燥时不可采用压缩空气，以免造成阿洛丁1200S膜层损伤。

2024-T3 aluminum alloy was treated with Alodine 1200S. The effects of raw materials, pre-treatment process, Alodine 1200S treatment time, content, pH and post-treatment on the salt spray corrosion resistance of 2024-T3 aluminum alloy were studied by salt spray test. The results show that in the pre-treatment stage of Alodine 1200S treatment process the effect of alkali cleaning should ensure the continuity of water film on the surface of Al alloy, and the deoxidization time should be 1-3 min. The optimal control range of Alodine 1200S content was 11.3-12.5 g/L, and the optimal pH range was 1.6-1.8. The spray device should not be used for water cleaning after Alodine 1200S treatment, at the same time, compressed air should not be used during drying to avoid damage to the Aoldine 1200S membrane.
