摘要

Heating the chloride electrolyte to a temperature of 70°C ensures the normal codeposition of thecomponents of the CoNiFe alloy as a result of the discharge of single-charged iron and cobaltspecies (Fe 2+ Cl - ) + and (Co 2+ Cl - ) + , respectively and double-charged Ni 2+ ions at a high cathodecurrent density. The chloride electrolyte obtained with filtration and pH correction by hydrochloricacid provides the electrochemical deposition of CoNiFe films with a C Co :C Ni :C Fe ratio of 1:1:1. Themechanism of the abnormal deposition of Co, Fe and Ni occurs due to the incomplete ionization ofatoms and differences in ion mobility. Based on the experimental results of CoNiFe films, anelectrochemical deposition mechanism is proposed. In contrast to the well-known in the literature,the phenomena occurring in the volume of electrolyte, including transmission of ions, with thedetermining effect is the mobility and formation of positive ions on the anode. CoNiFe films areproduced without mechanical stresses, with a uniform structure and with high magnetic parameterswithout a high burn temperature. Electrochemical deposition when the charge of ions in theelectrolyte is taken into account allows to obtaining a reproducible electrochemical deposition ofCoNiFe films.
