High Temperature Tribological Performance of Steel/Copper Friction Pairs Lubricated With a Modified C-WS2-(Fe3O4+TiN) Nanoadditives in Non-Copper Coated Solid Wires
Abstract:In this study, four kinds of nanoparticles: graphite, WS2, Fe3O4 and TiN were used as lubricating additives for steel/copper friction pairs to solve the problem of welding contact tube wear with non-copper-coated solid wire at high temperature. The single and composite nanoparticles have excellent dispersion stability in absolute ethanol under the action of the compound surfactant NaSTA+OA+PVP. The tribological test results showed that the maximum decrement with reference to the average coefficient of friction… Show more
