FIELD: metallurgy.
SUBSTANCE: composite material with nanoscale components to prevent biogrowth is composite granules of 0.5-500 mcm obtained by mechanical alloying for 0.2-2 hours under nonoxidation conditions. The granules contain a copper matrix and 25-60 vol. % of nanoscale components with a particle size of 2-50 nm. Nanoscale components are selected from a range of: nanodiamonds, nanopowders of silicon oxide, tungsten carbide, silicon carbide, titanium carbide, zirconium oxide, tungsten or steel. Nanoscale components are distributed throughout the volume of the granules and cover no more than 90% of the granules surface, on which copper oxides are present that are formed after mechanical alloying when the composite granules are in contact with oxygen.
EFFECT: increased metal oxidation effect in the presence of non-agglomerated nanoparticles on the surface ensures protection of the material from biogrowth.
