- 针对2024-T3铝合金传统三酸脱氧液中Cr6+存在严重危害环境问题，研究开发了2024-T3铝合金环保碱性脱氧工艺。通过正交试验对该工艺脱氧处理后的铝合金表面形貌、粗糙度进行分析，得到最佳碱性脱氧工艺参数为：碳酸钠80 g/L、表面活性剂0.2 g/L、缓蚀剂15 g/L、整平剂10 g/L、温度60 ℃、脱氧时间2 min。对该工艺处理后的铝合金进行阳极氧化及沸水封闭处理，膜层电化学交流阻抗测试容抗弧的容抗直径为120 306 Ω·cm2，中性盐雾试验超过500 h。
- Abstract:
- An environmentally friendly alkaline deoxidation process for 2024-T3 aluminum alloy has been developed to address the serious environmental hazards of Cr 6+ in the traditional tri-acid deoxidation solution. The surface morphology and roughness of aluminum alloy after deoxidation treatment were analyzed using orthogonal experiments. The optimum alkaline deoxidation process parameters are as follows: sodium carbonate 80 g/L, surfactant 0.2 g/L, corrosion inhibitor 15 g/L, leveling agent 10 g/L, temperature of 60 ℃, and deoxidation time of 2 min. The aluminum alloy treated by this process was subjected to anodizing and boiling water sealing treatment. The capacitance radius of the electrochemical impedance test for the film layer was 120 306 Ω·cm 2, and the neutral salt spray test exceeded 500 h
