ELECTROLYTE FOR PRECIPITATION OF COBALT-BISMUTH ALLOY Russian patent published in 2003 - IPC

FIELD: electroplating, instrumentation engineering. SUBSTANCE: invention can be used to secure coats displaying high corrosion resistance. Given electrolyte contains, g/l: cobalt chloride 40.0-60.0; bismuth chloride 5.0-15.0; Trilon Б 50.0-60.0; boric acid 20.0-30.0, equalizer A 2.5-3.5 and water. Technical result of invention consists in increased scattering power of electrolyte and corrosion resistance of obtained coats thanks to formation of metastable phase on cathode ( supersaturated solid solution of bismuth in cobalt and intermetallic compound CoBi ). EFFECT: increased scattering power of electrolyte and corrosion resistance of obtained coats. 1 tbl
