摘　　要：本文设计对比试验,测试三种不同组分的阳极在电阻率70~80ohm.cm的海泥介质环境下的电化学性能指标,目的在于探寻更适用于海泥介质的阳极组分。实验结果表明:改进配方的AZF01铝基阳极在高电阻率海泥介质环境中有较负的工作电位、较高的电化学容量和更好的溶解形貌,性能优于传统DNV标准组分AZF02、AZF03阳极。A comparative test was designed to test the electrochemical performance of three different components of anodes in the environment of sea mud medium with resistivity of 70~80 ohm.cm,for the purpose of exploring the anode components more suitable for Marine mud medium.The experimental results show that the modified AZF01 anode has more negative working potential,higher electrochemical capacity and better dissolution morphology in the environment of high resistivity sea mud,and its performance is better than that of AZF02 and AZF03 anode.
