摘要: 在ZnCl2镀槽中悬浮一定量的不溶性粒子,如石墨,PbO2,SnO2,TiO2,SiO2等,电沉积制备Zn粉,并对其结构、形貌及腐蚀行为进行分析.SEM的结果表明使用悬浮法可阻止Zn枝晶生长.悬浮PbO2,SnO2,TiO2,SiO2或In2O3等能明显地提高Zn粉在5mol/LKOH溶液中的缓蚀能力,此外,文中还应用分形理论对结果作了进一步的讨论.

Abstract: Zinc powders were electrodeposited from ZnCl 2 baths with containing suspension of unsoluble particles such as graphite, PbO 2,SnO 2,TiO 2, SiO 2 etc.. The structure, morphology and corrosion behavior of zinc powder were analyzed. SEM results showed that the dendritic growth of zinc can be inhibited by applying the suspension method. Suspension of PbO 2, SnO 2, TiO 2, SiO 2 and In 2O 3 could greatly improve the corrosion protection of zinc powder in 5 mol/L KOH. In addition, fractal theory is employed to further explain the results.
