研制了一种钌-钛-铱-锰氧化物涂层钛阳极,实验室研究和海上阴极保护实际试用表明,该电极在海水中有极化不大(100.0 A/m~2下不超过2V),耐高电流密度(8000A/m~2稳定工作超过三个月)消耗率低(3.1mg/A·Y)等优点。适合在海上阴极保护系统中试用。文中还讨论了钛-钌氧化物系电极钝化失效的原因,对改进这类电极性能的途径提出了看法。
A ruthenium-titanium-iridium-manganese oxide coated titanium anode was developed. The laboratory tests and practical tests of cathodic protection at sea show that the electrode has little polarization in seawater (less than 2V at 100.0 A / m 2) ), High current density (8000A / m ~ 2 stable work more than three months) low consumption rate (3.1mg / A · Y) and so on. Suitable for use in cathodic protection systems at sea. The paper also discusses the reasons for the failure of passivation of titanium - ruthenium oxide electrodes, and puts forward some suggestions on how to improve the performance of these electrodes.
