Congruent electrochemical deposition of NiFe alloy. The results of the research

      Аннотация: Electrodeposition is considered as an easy and cost effective technique for preparation of alloy coating. In our works selected chloride electrolyte with an attitude of Ni/Fe = 4.26, developed the technology of preparation of electrolyte and temperature is selected. This made it possible to establish a mechanism of anomalous deposition because of incomplete ionization of atoms of iron and ensure the congruent, i.e. the persistence, in the film a relationship Ni/Fe = 4.26 at room temperature, without mechanical stress, uniform structure and high magnetic properties, without high temperature annealing. Experimental results obtaining permalloy films specified composition found scientific justification in the form of exclusion from the chloride electrolyte ions bivalent and trivalent iron. At the same charge, nickel and iron ions undergo congruent permalloy deposition.
