Abstract:To analyze self-lubricating mechanism of copper-based graphite composites, the discrete element method (DEM) was used to study motion law of graphite particles of copper-based graphite composite/45 steel during friction. The research results show the film-forming particle layer was formed on the composite surface after a period of friction, which maintained dynamic balance depends on continuous supply of graphite in the composite. At different position, the trajectory of graphite particles is different, but th… Show more
