Zusammenfassung: | The invention discloses a conductive wear resistant material and a preparation method thereof. The conductive wear resistant material is prepared from the following components in parts by mass: 5 to 15 percent of C, 2 to 6 percent of Sn, 1 to 3 percent of Pb, 1 to 3 percent of Ni, 5 to 8 percent of Fe and the balance of Cu. In the invention, each component of the material is matched for use. The conductive wear resistant material has favorable electric conductivity and frictional property and can be used as friction pairs with a conductive friction function, such as a sliding plate in a bow net system of railways, a carbon brush in a motor and the like. Compared with a copper-based powder metallurgical material, the friction factor and the wear rate of the conductive wear resistant material added with 10 percent of graphite are both lowered, the wear-resisting property is obviously enhanced, the fluctuation of the friction factor under different current intensities and sliding speeds is decreased, and the fri |
