摘要
为了提高低温镀铁层的综合性能,扩大低温镀铁工艺的应用范围,分别探讨了镀液中不同CeCl3含量时低温镀铁的沉积速率、镀层的显微硬度、腐蚀速率和镀液抗氧化性等。结果表明:随着镀液中稀土Ce含量的增加,镀铁层的沉积速率增大,耐蚀性和镀液抗氧化性增强,镀铁层与基体的结合强度减弱;稀土Ce的添加可显著提高镀铁层的显微硬度,CeCl3浓度为0.5 g/L时,镀铁层的显微硬度最高,综合性能最佳。
The effect of CeCl3 content in plating bath on the anti-oxidation ability of the plating solution as well as the deposition rate, microhardness and corrosion rate of the Fe coating was investigated. It was found that with increasing content of CeCl3 in the plating bath, the deposition rate and corrosion resistance of Fe coating increased, and the anti-oxidation ability of the plating solution rose. However, the adhesion of Fe coating to substrate declined. In one word, introducing Ce into the plating bath helped to significantly increase the microhardness of low-temperature electroplated Fe coating; and Fe coating deposited at a CeCl3 concentration of 0.5 g/L had the highest microhardness and the best comprehensive properties.
