The purpose of the given research has been to specify the route of formation of Co–W coatings. To this end, the gel-chromatographic separation of gluconate electrolyte has been used, as well as the photocolorimetric determination of the composition of the separation products, and the evaluation of the electrochemical activity of these complexes in the pH range of 4.0 to 8.0. As a result, it has been found out that the composition of the Co–W coatings thus formed is defined by the relation of the rates of the reduction of those heterometallic complexes (with the Co–W ratio 1 : 1) and Co complexes in solution, as well as the reaction of hydrogen reduction, dependent on both the electrolyte pH and hydrodynamic conditions. |
