FIELD: chemistry.
SUBSTANCE: invention relates to methods of anticorrosive surface treatment of aluminium articles. Surface of article is subjected to pulse power action by radiation of pulsed fibre-optic ytterbium laser with wavelength of 1.065 mcm at specific radiation power of 4.539⋅1010…8.536⋅1010 Wt/cm2, pulse repetition rate 20…40 kHz and surface scanning speed by laser radiation 250…700 mm/s. Hydrophobisation of the surface is then carried out with an aqueous solution of vinyltriethoxysilane.
EFFECT: technical result is obtaining on surface of article made of aluminium of tight impermeable passive hydrophobic film of aluminium oxide, effectively protecting metal from corrosion.
