FIELD: chemical deposition.
SUBSTANCE: invention relates to the field of chemical deposition of cobalt on the surface of products subject to erosion, and in particular to a composition for the chemical deposition of a cobalt coating on the surface of products with an irregular shape. The specified composition contains the following ratio of components in water, g/l: cobalt chloride (CoCl2) 60-90, sodium hypophosphite (NaH2RO2⋅xH2O) 60-120, citric acid (C6H8O7) 80-100, aminoacetic acid (glycine) (NH2CH2COOH) 15-35, sodium carbonate (Na2CO3) 20-40, ammonia water 25% (NH4OH) 30-50.
EFFECT: obtaining a composition allowing to deposit cobalt on the surface of products with an irregular shape at an increased rate and at the same time maintaining long-term stability.
