FIELD: chemistry.
SUBSTANCE: method involves zinc plating, nickel plating. After nickel plating heat treatment is carried out at a temperature of 210°C for a period of 60 minutes followed by activation in concentrated hydrochloric acid at a temperature of 15-30°C for 1 minute.
EFFECT: simplification in preparing the surface of articles made from aluminium or its alloys before electroplating.
