研究了硫酸盐和氯化物电解液中电沉积铁粉过程中的极化特性及所得粉末的形貌。在所研究的范围内，形貌与电解液中阴离子的存在有关，而与电流密度无关。从硫酸盐电解液中获得的具有菜花状末端的树枝状粉末的特征性特征是存在锥形空腔和粉末表面的晶体形貌。而在氯化物电解液中沉积的铁粉则以团聚体的形式存在.作为洗涤和干燥方法应用的肥皂溶液处理可以提供良好的保护，防止粉末氧化。
Polarization characteristics of the electrodeposition processes of Fe powders from sulfate and chloride electrolytes and the morphology of the ob- tained powders were investigated. The morphology depended on the anion pre- sence in the electrolyte but not on the current density in the investigated range. A characteristic feature of the dendritic powder with cauliflower endings ob- tained from sulfate electrolyte is the presence of cone-like cavities and the crys- tallite morphology of the powders surface. On the other hand, Fe powders elec- trodeposited from chloride electrolyte appear in the form of agglomerates. A soap solution treatment applied as a method of washing and drying provides good protection from oxidation of the powders.
