FIELD: powder metallurgy, namely antifriction powder materials, possibly application of coatings on steel parts, for example in machine engineering.
SUBSTANCE: material for applying antifriction coatings of mechanically alloyed alloy in the form of powder contains, mass %: lead, 4 -22; copper, 0.4 - 1.0; aluminum, the balance at next relation of fraction sizes: 1 - 50 micrometers, 5 - 30%; 51 - 160 micrometers, 70 - 95 %. At preparation of such material, mixture of powders of aluminum, lead, copper or their alloys is blended for 0.5 - 2 h while using aluminum pellets 5 - 20 mm as working bodies. Then charge is subjected to mechanical working in high-power mill at power content 3 -30 kWt/kg for 0.5 -10 h.
EFFECT: enhanced wear resistance, lowered friction factor of coating.
