摘　　要：在销—盘式磨损试验机上用 4 5钢—铜摩擦副进行了磨损试验 ,用扫描电子显微镜拍照分析 ,发现磨粒的外形轮廓存在着分形特征 ,且磨粒分形维数的变化同磨损状态有一定的对应关系 ,因此对磨粒分形维数的考察有助于了解磨损状态的转变。The wear test of AISI1045 steel sliding against copper disc was carried out on a Pin_on_disc test rig.The wear debris produced in different period were collected in order to count and analyze.The results indicate that a fractal behavior was showed about boundary of wear particles.Moreover,the change of wear particles fractal dimension is related to the wear process.This could be informative and helpful to the identification of wear states.
