FIELD: chemistry.
SUBSTANCE: method involves defatting, washing in hot water, washing in cold flowing water, activation and washing in cold flowing water before applying a metal coating, characterised by that activation is carried out at temperature of 18-22°C for not less than 10 minutes in a solution of the following composition: sodium hypophosphite 8-10 g/l, hydrofluoric acid 2-4 g/l, distilled water - up to 1 l.
EFFECT: high quality of coatings while cutting the number of operations.
