摘要
通过采用电化学性能测试、极化测试和电化学阻抗测试等方法评价了研制的深海牺牲阳极在模拟深海环境中的性能,并与常规环境进行对比。结果表明,深海阳极在模拟深海环境中的电流效率达95%,实际电容量大于2 700 A·h/kg,工作电位接近-1.1 V,溶解形貌良好,腐蚀产物脱落,整体电化学性能优异,但受深海低温低氧环境影响,深海阳极在模拟深海环境中的发出电流量及反应活性略低于常规环境。
The electrochemical behaviour of deep-sacrificial anode developed was evaluated in a simulated deep-sea environment through electrochemical performance test,polarization and electrochemical impedance test. The results showed an excellent electrochemical performance of these anodes in deep-sea environment. The current efficiency of the anode reached 95%,the actual capacity of more than 2 700 A·h / kg,the working potential of about- 1. 1 V,the dissolution morphology was uniform.There was no corrosion product adherent to the anode surface,but the current output and reactivity in deep-sea slightly lower than which in shallow area,due to the impact of low temperature and low oxygen.
