FIELD: technological processes; metallurgy.
SUBSTANCE: invention is related to method for provision of protective coat containing aluminium on metal substrate surface. Substrate and non-gaseous predecessor that contains aluminium are installed in chamber, and substrate is treated at the temperature in the range of 950-1200°C and in atmosphere that contains active gas that reacts with predecessor for creation of gaseous compound of aluminium. Produced compound decomposes in contact with substrate, providing application of metal aluminium on this substrate. Mentioned atmosphere comprises gaseous compound of metal-modifier, which decomposes in contact with substrate, providing application of mentioned metal-modifier on it together with deposition of aluminium.
EFFECT: protective coat on substrate that makes it possible to preserve its operational properties.
