Influence of long-term operation of electrolytes on the composition, morphology, and mechanical properties of surfaces produced at deposition of Co-W coatings from citrate solutions

Year: 2009

Type: article

Abstract: A comprehensive study has been conducted on the composition of a citrate electrolyte used to produce Co-W coatings that contains (mol/l) the following: cobalt sulphate (0.2), sodium tungstate (0,2), citric acid, sodium citrate, boric acid (pH 6.5) at both its storage and long electrolysis (up to Q ≈ 17 A hour/l). The influence of the degree of operation, the electrolyte agitation, and current volume density on variations in its composition, as well as on the coating composition and microhardness is shown. The observed variations arise from the Podlaha-Landolt induced codeposition mechanism as applied to the used electrolyte composition and electrolysis modes.
