FIELD: galvanized steel processing.
SUBSTANCE: invention is related to processing of zinc-coated steel products and can be used to combat corrosion in the car building, shipbuilding, agricultural and other industries. The method of passivation of galvanized steel consists of treatment of galvanized steel with neodecanoic acid vapors in a closed space at a temperature of 80-140°C.
EFFECT: provision of high corrosion resistance of the zinc coating.
