摘要
本文通过SEM、EDS等分析方法,采用浸泡失重测试了不同杂质元素含量的Mg-Mn牺牲阳极材料的腐蚀速率及阳极效率。试验结果表明,杂质元素Fe、Si等元素与镁基体形成电偶腐蚀,加速了合金的腐蚀速率,从而降低了其阳极利用率,导致阳极效率低于50%,不符合镁阳极材料的要求。
In this paper,the corrosion rate and anode efficiency of Mg-Mn sacrificial anode materials with different impurity element contents were tested by SEM,EDS and other analytical methods using immersion weight loss.The test results show that the impurity elements Fe,Si and other elements form galvanic coupling corrosion with magnesium substrate,accelerating the corrosion rate of the alloy,which reduces its anode utilisation rate,resulting in anode efficiency lower than 50%,which is not in line with the requirements of magnesium anode materials.
