 The bearings also improve wear characteristics because deformation of the graphite particles results in the formation of a continuous graphite film, which provides self-lubrication of the component, allowing for improved component longevity.These materials could benefit virtually all journal bearings in the power train.Selectively reinforced functionally gradient bearings of aluminum-graphite and copper-graphite alloys can be manufactured in a single step by centrifugal casting of metal-graphite suspensions (Figs.
