METHOD FOR PRODUCING A COMPOSITE MATERIAL AND A PRODUCT THEREFROM Russian patent published in 2022 - IPC C22C1/10 B22F1/00 B22F9/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy and can be used to produce composite materials with a metal matrix and coatings. Method for producing an aluminium matrix composite material containing an aluminium matrix and a ceramic reinforcing agent includes processing the base mixture of aluminium powders and elements forming the ceramic reinforcing agent by mechanical alloying, wherein the mechanical alloying is performed in ball grinding and mixing units with a power rating of 0.02 to 2 kW/l for 0.5 to 30 hours in an argon medium, the processed powder mixture is placed in a thin-walled tube of a material similar to the matrix material, forming an electrode, which is heated to the temperature of the start of an exothermic reaction, followed by crystallising the formed melt droplets on a metal substrate by moving the electrode, forming a continuous layer of a composite material with a predetermined composition.

EFFECT: production of a composite material containing a metal matrix and high-melt reinforcing agents, with a homogeneous dense structure.
