研究了钛铁硼永磁体磁场对中碳钢摩擦磨损的影响.当磁场为45mT时，环和块的磨损量分别下降约50％和60％，进一步增加磁场磨损量则缓慢下降，至193mT时，环和块平均降低达70％，摩擦系数降低约30％．分析表明，磁场导致氧化磨损的比例增加是磨损降低的主要原因．
The effect of ferromagnetic iron-titanium magnets on the friction and wear of medium carbon steel was investigated. When the magnetic field was 45mT, the wear of the rings and blocks decreased by about 50% and 60% respectively, while the wear of the magnetic field decreased slowly. , Ring and block average reduction of 70%, the friction coefficient decreased by about 30%. The analysis shows that the increase of the proportion of oxidation wear caused by the magnetic field is the main reason for the decrease of wear.
