中文摘要: |
以硫酸盐和氯化盐为主盐,将Cr以微粒形式悬浮于镀液中,电沉积Fe-Cr-Ni复合镀层,用电化学方法研究了镀液中Cr粉含量对电沉积Fe-Cr-Ni复合镀层在NaCl介质中的腐蚀行为的影响。结果表明:在镀层的浸泡试验中,溶液中Cr粉含量为lOOg/L获得的镀层自腐蚀电位是最负的。动电位扫描显示,镀层都有钝化性能。但对于溶液中Cr粉含量为lOOg/L获得的镀层出现明显的过钝化,其耐蚀性能较差。 |
英文摘要: |
The Fe-Cr-Ni coating was electrodeposited from chloride-sulphate electrolyte. The effect of the content of Cr in electrolyte on the electrochemical corrosion behavior of electrodeposited Fe-Cr-Ni coating in NaCl solution was investigated. The results show that the corrosion potential of the coating is negative when the content of Cr is lOOg/L during immersion test. In addition, the coating shows passivation behavior. When the content of Cr is lOOg/L in the electrolyte, the coating shows overpassivation phenomenon, and then the coating exhibits poor corrosion resistance. |
