APPLICATION OF ATOMIZED COPPER POWDER IN OBTAINING COPPER--GRAPHITE CONTACTS

The method of decomposing salts makes it possible to obtain materials which, by their tribotechnical and electrocontact properties, are not inferior to the standard materials for electric brushes brands MG, MGSOA. The oriented laminated structure of fine-grained copper in graphite causes the formation of surface layers that are characteristic of normal mechanochemical wear. This improves the wear resistance of the material and stabilizes its electrocontact characteristics.
