FIELD: technological processes.
SUBSTANCE: invention relates to protection of metals against corrosion. Method includes treatment of metal surfaces with multimodal roughness in hydrophobizator vapors at high temperature from 60 to 150 °C, wherein the hydrophobizator used is stearic acid, lauryl acid, salts thereof with octadecylamine, octadecylamine and mixture thereof with benzotriazole (1:1 by weight).
EFFECT: higher anticorrosive protection of steel, copper, zinc and aluminum alloys.
