同一种成份的牺牲阳极材料在不同介质中电化学性能存在着明显差异,这说明介质对阳极性能有较大影响。为提高阴极保护效果,在现有商用阳极的基础上研制出适合大港滩海环境的AZI-Mg-SiGa系和AZI-MgBi系新型铝合金牺牲阳极。该阳极综合电化化学性能优良,在海水、海泥介质中适应性强,工作电位负且平稳,在海泥中电流效率>70%,可作为优异的阳极材料加以应用。
The same composition of sacrificial anode material in different media electrochemical performance there is a clear difference, indicating that the medium has a greater impact on the anode performance. In order to improve the cathodic protection effect, AZI-Mg-SiGa and AZI-MgBi sacrificial anodes were developed on the basis of the existing commercial anodes. The anode is characterized by its excellent electrochemical performance, strong adaptability in seawater and marine mud medium, negative and stable working potential, and current efficiency> 70% in sea mud, which can be used as an excellent anode material.
