FIELD: FIELD inorganic chemistry.
SUBSTANCE: invention refers to metal protection from oxygen corrosion by inhibitors. Inhibitor has the ratio, mass%: m-niterobensal - p-iodoaniline 14.8-17.9; 4.5 dichlor-2-threeflouromethylbenzimidazole 33.3-23.9; urotropine51.9-58.2. The technical result: inhibitor effectively protect from corrosion the steel, aluminium and titanium in dipping, chlorohydric and ortho-phosporic acids, don't let developing to hydrogen charging of the steel, besides inhibitor can be used for etching operation of steel, aluminium and titanium, and also for acid treatment of the devices of the mentioned metals.
EFFECT: it is achieved inhibitor for steel protection in acids and for etching operation of steel.
