| Abstract: | Magnesium sacrificial anodes with different Mn contents, i.e. 0.08%, 0.2%, 0.3%, 0.4%, 0.5% and the Mg-1Mn (0.6% and 0.7% Mn), which was used mainly in engineering applications were prepared by highly purified magnesium. The effects of Mn content on diminishing the Fe content, the microstructure and the electrochemical properties of Mg-Mn anodes were investigated. In addition, the availability of decreasing the Mn content of the Mg-Mn high potential sacrificial anode was proved and the proper Mn addition scale was also determined. |
