Abstract

The heat-resistant nickel- and nickel-molybdenum electroplatings of high quality were prepared on copper and aluminum bases using the method of galvanic electrolysis. The platings are uniform, non–porous and are characterized by high adhesion. The optimal parameters of the process (current density, electrolysis duration, ratio between anode currents of molybdenum and nickel) are determined. MicroX-ray and fluorescence analyses of the obtained samples are carried out. Molybdenum content in the plating is determined. The existence of fine-dispersed phases of MoNi3 and MoNi4 are established. Electrical and mechanical properties of above – mentioned platings are studied after the heat treatment for their operation at high temperatures.
