Electrodeposition of bright Al and Al-Mn coatings from AlCl3-EMIC ionic liquid

doi:10.11949/j.issn.0438-1157.20141886

Abstract

Abstract:

Electrodeposition of bright Al and Al-Mn were carried out in AlCl₃-1-ethyl-3-methyl-imidazolium chloride (AlCl₃-EMIC) and MnCl₂-AlCl₃-EMIC ionic liquid with additives. The effects of the additive on the morphology, structure and brightness of the coatings were studied. The mechanism of brightening was discussed. The morphologies and structures of the coatings were characterized by SEM and XRD, respectively. The brightness of the coatings were characterized in the capability of reflecting images in the coatings. The results showed that ultra-bright Al and Al-Mn coatings were electrodeposited with the additives. The brightness of coating increased with the concentration of additive. The ultra-bright Al coating was nanocrystals with a preferred crystallographic orientation, while the ultra-bright Al-Mn coating was amorphous particles in nanometers. The brightening of coating is attributed to the grain refinement and preferred growth of the coating caused by the additive.

摘要：

通过添加光亮剂, 分别在AlCl₃-氯化1-甲基3-乙基咪唑(AlCl₃-EMIC)和MnCl₂-AlCl₃-EMIC离子液体中电沉积Al和Al-Mn镀层, 重点研究了光亮剂对镀层形貌、结构以及光亮性的影响, 探讨了镀层光亮的机理。采用扫描电镜(SEM)和X射线衍射(XRD)对镀层形貌和结构进行观察和分析, 以镀层对图案的反射能力大小对光亮度进行表征。结果表明, 添加光亮剂之后, 可以电沉积出具有镜面光亮的Al和Al-Mn镀层, 并且镀层的光亮度随光亮剂浓度的增加而增加。光亮Al镀层为具有择优取向生长的纳米晶体, 而光亮Al-Mn则是纳米尺寸的非晶颗粒。镀层光亮的产生是由于光亮剂细化了Al晶粒和Al-Mn非晶颗粒, 同时使Al晶体择优取向生长造成的。
