摘要
采用纯度较高的纯镁为原料熔炼了Mn含量分别为0.08%,0.2%,0.3%,0.4%,0.5%(质量分数)的低Mn含量镁牺牲阳极和工程中常用的Mg--1Mn合金(Mn含量为0.6%,0.7%),探讨Mn含量对降低Mg-Mn牺牲阳极Fe含量、显微组织和电化学性能的影响规律,阐明低Mn含量镁牺牲阳极的工程应用可行性,得到合理的Mn含量范围。
Magnesium sacrificial anodes with different Mn contents, i.e. 0.08%, 0.2%, 0.3%, 0.4%, 0.5% and the Mg-lMn （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.
