1AlCl_3-EMIC离子液体电沉积光亮Al和Al-Mn镀层显示文摘通过添加光亮剂,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。薛东朋 徐霸津 陈益明 张仇 凌国平 2015化工学报2015,66,S1:4
2Anodic dissolution of metals in ionic liquids显示文摘The anodic dissolution of metals is an important topic for battery design,material finishing and metal digestion.Ionic liquids are being used in all of these areas but the research on the anodic dissolution is relatively few in these media.This study investigates the behaviour of 9 metals in an ionic liquid [C_4mim][Cl] and a deep eutectic solvent,Ethaline,which is a 1:2 mol ratio mixture of choline chloride and ethylene glycol.It is shown that for the majority of metals studied a quasi-passivation of the metal surface occurs,primarily due to the formation of insoluble films on the electrode surface.The behaviour of most metals is different in [C_4mim][Cl] to that in Ethaline due in part to the differences in viscosity.The formation of passivating salt films can be decreased with stirring or by increasing the electrolyte temperature,thereby increasing ligand transport to the electrode surface.Andrew P.Abbott Gero Frisch Jennifer Hartley Wrya O.Karim Karl S.Ryder 2015Progress in Natural Science:Materials International2015,25,6:2
