    Electrodeposition of functional cobalt-silver and cobalt-tungsten alloys
    (Publishing House of Lviv Polytechnic National University, 2014) Ved, Marina; Sakhnenko, Nikolay; Glushkova, Marina; Bairachna, Tetiana
    The kinetic mechanism of cobalt-silver and cobalt-tungsten alloys electrodeposition from citratepyrophosphate and citrate electrolyte correspondingly has been established. The influence of electrolyte component ratios as well as polarization pulse on/off time ratios on cobalt alloy composition and its current efficiency has been determined. The cobalt-silver and cobalt-tungsten alloys have been shown to possess catalytic and anticorrosion properties. Встановлено механізм осадження сплавів кобальту з нешкідливих електролітів. Виявлено вплив компонентів електроліту та шпаруватості поляризованих імпульсів на склад сплавів кобальту та їх вихід за струмом. Показано, що сплави кобальт-срібло та кобальт-вольфрам володіють каталітичними та протикорозійними властивостями.
