PROCEDURE FOR PRODUCTION OF COMPOSITE ELECTRO-PLATE NICKEL-COBALT-ALUMINIUM OXIDE AND COMPOSITE ELECTRO-PLATE NICKEL-COBALT- ALUMINIUM OXIDE

摘要

FIELD: metallurgy.;SUBSTANCE: procedure consists in settling plate from electrolyte containing, g/l: nickel chloride 200-350, cobalt chloride 3-11, aluminium oxide 15-40, boric acid 25-40, chloramines B 1.5-4.0, at pH of electrolyte 1.5-5.0, temperature 18-40 °C, cathode current density 0.5-9.0 A/dm² and in electrolyte mixing. Plate contains, wt %: cobalt 1.8-6.7, aluminium oxide 1.2-3.8, nickel - the rest.;EFFECT: raised wear resistance, adhesion and glide of plate.;2 cl, 2 tbl, 5 ex
