FIELD: corrosion protection.
SUBSTANCE: invention relates to the field of prevention of corrosion in aqueous solutions in the industry and power engineering by creation of protective film on a metal surface. The method includes creation of protective coating on a metal surface, while an aqueous solution is taken for processing of the metal surface, containing 100-200 mg/l of nitrilemethylenephosphonic acid and 8-16 mg/l of zinc oxide or salt per metal, processing of the metal surface is carried out for at least 6 h and up to 24 h to form protective coating with a thickness of at least 60 nm and up to 420 nm.
EFFECT: increase in the efficiency of corrosion processing by creation of protective coating in the form of film on a metal surface, including a metal surface of large-scaled parts.
