| 摘 要： | 在AlC13-EMIC室温熔盐体系中,在201不锈钢基体上电沉积了铝镀层,并利用金相显微镜、能量色散谱和扫描电镜对镀层的成分、表面形貌及镀层与基体之间的结合情况进行了观察分析.结果表明,201不锈钢基体可以通过AlC13-EMIC室温熔盐电沉积的方法获得完整平滑且纯度较高的铝镀层.铝镀层晶粒尺寸随电流密度变化较为明显,随电流密度的增大,晶粒尺寸变小,镀层更加致密化.在电沉积前,通过阳极活化对不锈钢基体进行预处理,可以使铝镀层和不锈钢基体的结合得到显著的提高；通过对电沉积后试样进行热处理,可以提高铝镀层和基体之间的结合力.

| Abstract: | The feasibility of electrodeposition aluminum on 201 stainless steel from AlC13-EMIC room temperature molten salts was studied. The composition and morphology of coating and the adhesion between the coating and the substrate were observed and analyzed by energy dispersive spectroscopy (EDS) and scanning electron microscope (SEM). The results showed that whole aluminum coating with high purity can be electrodeposited on 201 stainless steel from AlC13-EMIC room temperature molten salts. The grain size of aluminum coating became smaller and the coating become denser when the current density increased. It was found that anodizing before electrodeposition or heat treatment after the electrodeposition can significantly improve the adhesion between the aluminum coating and the substrate． |
