摘要

摘要: 研究了铝合金阳极在低温条件下的电化学性能，在2~3℃低温条件下，对铝合金牺牲阳极电化学性能进行了DNV-RP-B401-2011测试和NACE-TM0190-2006测试，结果表明，同种化学成分的条件下，样品1的溶解形貌和电化学数据均好于样品2的结果，3种不同成分的铝合金阳极中，样品4的电化学性能结果最好。在2~3℃低温环境下，由于活性元素的反应活性更弱，铝合金牺牲阳极电化学性能DNV-RP-B401-2011测试结果与NACE-TM0190-2006测试结果相比，前者溶解形貌要更差一些。阳极中微量元素的精确控制和均匀分布，对铝合金牺牲阳极的电化学性能和溶解性能影响较大。

Abstract: The electrochemical properties of aluminum alloy sacrificial anode were detected by DNV-RP-B401-2011 method and NACE-TM0190-2006 method, and the electrochemical properties and the morphologies of anode dissolution of different aluminum anode components were analyzed under these conditions. The results showed that under the condition of the same chemical composition, the dissolution morphology and electrochemical data of sample 1 were better than those of sample 2, and the electrochemical performance of sample 4 was the best among the three different components of aluminum anode. In the low temperature environment of 2~3℃, due to the weaker reactivity of active elements, the electrochemical properties of aluminum alloy sacrificial anode were more poorly by DNV-RP-B401-2011 accelerated method than those by NACE-TM0190-2006 method. The precise control and uniform distribution of trace elements in the anode had great influence on the electrochemical performance and solubility of the sacrificial anode of aluminum alloy.
