FIELD: chemistry.SUBSTANCE: invention relates to composite materials, particularly to metal matrix composites and can be used in making friction bearings. The metal matrix composite contains the following, wt %: antimony - 10.0-12.0, copper - 0.5-1.5, silicon carbide - 1.0-15.0, carbon nanotubes - 0.5-10.0, tin - the balance.EFFECT: material has improved antifriction and mechanical properties and high temperature resistance in conditions where the friction pair operates with limited lubrication or short-term dry friction.2 tbl |
