ВЛИЯНИЕ ДЛИТЕЛЬНОСТИ ПРОРАБОТКИ ЭЛЕКТРОЛИТА НА СОСТАВ, МОРФОЛОГИЮ И МЕХАНИЧЕСКИЕ СВОЙСТВА ПОВЕРХНОСТЕЙ, ПОЛУЧАЕМЫХ ПРИ ОСАЖДЕНИИ Co-W ПОКРЫТИЙ ИЗ ЦИТРАТНЫХ РАСТВОРОВ

Аннотация

It was carried out a complex of research of citrate electrolyte composition applied for obtaining of Сo-W films and containing (mol/l): cobalt sulphate (0,2), sodium wolframate (0,2), citric acid, sodium cit- rate, boric acid (рН = 6,5) both at its storage, and at long electrolysis (to Q ~ 17 A. hour/l.). Influence of de- gree of study, of electrolyte agitation and of current density volume on changes of its composition, and also films structure and their microhardness is shown. Observable changes are as a consequence of induced code- position mechanism of Podlaha-Landolt concerning to the used electrolyte composition and electrolysis modes.
