Electrodeposited Films of Iron-Nickel-Molybdenum Ternary Alloys

In the iron-nickel-molybdenum system of alloys there is a region of compositions characterized by high values of magnetic permeability and low coercive force. Of great interest are the alloys in this system possessing uniaxial magnetic permeability, a rectangular hysteresis loop, as well as alloys with high specific resistance. Such annoys can serve as the base for magnetic films used in computer technology and shf engineering. Most works on the properties of films of the ternary system Fe-Ni-Mo are devoted to films made by vacuum evaporation; there are very few studies on electrodeposited films of this system. This is explained by the insufficient development of a method of electrolytic deposition of films, as well as the difficulties involved in using this method with alloys containing molybdenum. Given references are devoted to the study of the electrodeposition of molybdenum with metals of the iron group. The process of electrolytic deposition of such alloys and their properties depend greatly on the mode of deposition - the cathodic density of the current, the acidity and temperature of the electrolyte. However, because of the lack of information on the character of this relationship, the mode of electrodeposition for the given system is generally selected experimentally.
