Abstrakt: Here, by the example of galvanostatic electrodeposition of Co–W coatings from a citrate bath, we demonstrate experimentally that when using the results on the deposition rate and the composition and properties (microhardness) of resulting coatings observed under laboratory conditions to develop this type of an electrodeposition process on a larger (industrial) scale the bath volume must be scaled in proportion to the increase in the cathode area. In this case, the current loading on the electrolyte, which is quantitatively expressed as the volume current density, does not increase. [ABSTRACT FROM AUTHOR]
