Research Progress on Tribological Properties of Self-lubricating Materials Liner for Spherical Bearings

The tribological property of the self-lubrication materials investigated by numerous studies in recent ten years is reviewed. The tribological properties of the liners for metal matrix,ceramic matrix and polymer matrix composites are mainly analyzed. It is proposed that the research problems may exist in self-lubrication liner of spherical bearings. It is suggested that high strength,wear-resistant and corrosion-resistant materials are the future research topics in self-lubrication liner.
