METHOD OF PRODUCING SHINY NICKEL COATINGS Russian patent published in 2016 - IPC C25D3/12 

FIELD: electroplating.

SUBSTANCE: invention relates to the field of electroplating and can be used for machining of parts in instrument and mechanical engineering, in the manufacture of household goods, surgical and laboratory instruments. Method includes application of standard electrolyte containing nickel sulphate, nickel chloride, boric acid and brightener. Electrolysis is carried out at a temperature of 50 °C and a current density of 5.0-6.0 A/dm², while trichlorethylamide derivatives in a concentration of 0.3-0.7 g/l with the structure

are introduced into the electrolyte as a brightener.

EFFECT: technical result: reception of shiny surfaces with high current yield and low porosity of coating, as well as diversification of brightening agents.
