摘要
在１７５℃下实验测得ＭｎＣｌ２在ＮａＡｌＣｌ４熔体中的溶解度为０．０８６±０．００６ｍｏｌ％。锰可以在阴极上与铝发生共电沉积，生成含锰量为８ａｔｏｍ％～１０ａｔｏｍ％的二元合金。铝锰共电沉积可以显著地加快电化学成核步骤，从而完全消除低电流密度下絮状沉积产物的生成，且对高电流密度下枝晶产物的生成也有抑制作用。
It was determined that the solubility of MnCl2 in the molten NaAlCl4 at 175℃ was 0. 086±0. 005 mol %. Mn can be electrolytically deposited on the cathode with Al forming a smooth layer of Al-Mn binary alloy which contains (8-10) atom % Mn. The codeposition of Al-Mn alloy can significantly speed the electro-nucleation process so as to avoid the formation o f spongy deposits completely at lower current density, and reduce the formation of dendritic or porous deposits at higher current density.
