摘　　要：大量研究表明,在金属摩擦副接触面间外加一适当的直流或交流磁场或预先将金属磁化.均可明显提高其耐磨性。磁场条件下的摩擦磨损特性研究,可开辟一条新的抗摩减磨途径。综述了近年来国内外对磁场条件下铁磁性材料摩擦学性能与机理的研究,对该方向的研究前景进行了展望。Numerous researches indicate that wear resistance of metals can be improved greatly by a properAC or DC magnetic field orpre-magnetizing. The studies of friction and wear behavior in a magneticfield can break a new way to reduce friction and wear. It is summarized that the investigation on tribological properties and mechanisms of ferromagnetic materials under a magnetic field in recent years at home and abroad. The prospects of magnetic tribology are proposed.
