Abstract
Study of the electrochemical activity of fractions of boron-gluconate electrolyte used for the manufacturing of nanocrystalline Co–W coatings (the fractioning is performed based on the different molecular weights of the solution components) shows that the electrodeposition results in the formation of an alloy with a very low concentration of tungsten (~1% at.) only from the fractions with a high molecular weight. Electrodeposition from the low-molecular fraction that contains chloride, boron-gluconate, and wolframate ions with cobalt inclusions is not observed. The obtained results are found to be described correctly by the Podlaha–Landolt model of the induced codeposition of iron-group metals with refractory metals.
