The aim of the described work was elaboration, by powder metallurgy methods, of chemical composition and manufacturing technology for modern composite materials. Having high abrasion resistance in highly difficult labour-conditions. The object of interest were composites on the matrix of high-speed steels, of the type: high speed steel - copper, high speed steel - tungsten carbide - copper, with concentration: 0/30 percent WC and 7,5/45 percent Cu. The parent substance was the powder of high speed steel M3/2, the powder of tungsten carbide WC, and the electrolytic copper-powder.
