Электрохимическое осаждение Co-Mo-W и Co-Mo-Zr покрытий из комплексных электролитов

Abstract

The regularities of ternary Co-Mo-W and Co-Mo-Zr alloys deposition from citratepyrophosphate electrolytes in galvanostatic and pulsed modes are established. It is proved that the composition and current efficiency of the alloys depend on the nature of the alloying metals and the electrolysis duration. Сitrate-pyrophosphate electrolytes of Co-Mo-W and Co-Mo-Zr alloys deposition have a high scattering ability, and for the Co-Mo-W electrolyte in the current density range 0,5–1,5 A/dm2, the value of this parameter is more than 90%.
