FIELD: technological processes.
SUBSTANCE: invention relates to a method for creating intermetallic coatings based on NiAl and Ni3Al compounds. Carry out the mechanical activation treatment in a ball mill for 30–60 minutes together with the metal product to be coated. This is followed by laser treatment of the obtained coating with a capacity of 100–200 W and with a scanning speed of 40–80 mm/s. Various metals and alloys, such as steel, titanium, aluminum, and nickel, are used as substrates. As a coating is applied a mixture of powders of Ni and Al in a ratio of 1:1 by weight.
EFFECT: obtaining coatings with high hardness and corrosion resistance, with the replacement of long-term annealing for high-performance laser processing.
