Electrodeposition of Fe powder from acid electrolytes
Elektrohemijsko taloženje Fe prahova iz kiselih elektrolita
Abstract
Polarization characteristics of the electrodeposition processes of Fe powders from sulfate and chloride electrolytes and the morphology of the obtained 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 obtained from sulfate electrolyte is the presence of cone-like cavities and the crystallite morphology of the powders surface. On the other hand, Fe powders electrodeposited 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.
U ovom radu prikazani su rezultati ispitivanja polarizacionih karakteristika procesa taloženja Fe prahova iz sulfatnih i hloridnih elektrolita, kao i morfologija dobijenog praha. Utvrđeno je da morfologija čestica zavisi od vrste anjona prisutnih u elektrolitu, ali ne i od primenjene gustine struje u ispitivanom opsegu. Karakteristično za čestice koje su istaložene iz sulfatnih elektrolita je da su one dendritične sa karfiolastim, kristaliničnim završecima i da poseduju kupaste šupljine. Kod Fe prahova istaloženih iz hloridnih elektrolita uočeni su aglomerati. Korišćenje rastvora sapuna u procesu pranja i sušenja prahova pokazao se kao dobar metod zaštite praha od oksidacije.
