Abstract
The paper presents an effect of applying and directing a constant magnetic field on electrodeposition and magnetic properties of refractory metal alloys (W, Mo, Re) with cobalt deposited from citrate-pyrophosphate electrolytes. A mathematical model is presented that describes the creation of convective flows due to the micro-MHD effect in near-surface layers during electrodeposition of a ferromagnetic alloy in a magnetic field. It has been found that the greatest influence of the magnetic field applying on the electrodeposition of alloys under investigation is observed for rhenium ones, that is, there is a decrease in the rhenium content from 40 to 8 at.% (compared with deposition without magnetic field) and a halving of crystallite sizes. The magnetic properties of the resulting coatings depend on the nature of the refractory metal and can vary over a wide range.
