ELECTROLYTE FOR ELECTRODEPOSITION OF TIN-COBALT COATINGS

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to electroplating, particularly for production of galvanic coatings with tin-cobalt alloys on steels or copper, and can be used in electronic industry, machine building, instrument making, automotive industry and other industries. Electrolyte contains, g/l: tin sulfuric 5–20, cobalt sulfuric acid 5–10, ammonium oxalate 80–100, preparation OC-20 0.4–0.6 and water up to 1 litre.;EFFECT: reduced corrosion of coatings with simultaneous reduction of environmental load on natural water due to reduced toxicity of waste water.;1 cl, 2 tbl
