摘　　要：The dependence of tribology behavior of hard disk on scanning velocity was investigated by friction force microscopy in both air and vacuum. It is found that the sur-face friction force decreases with increasing scanning velocity in air as well as in vacuum. In vacuum, due to the capillary force disappearing, the adhesive energy decreases signifi-cantly, and the friction force is much smaller than that in air.The dependence of tribology behavior of hard disk on scanning velocity was investigated by friction force microscopy in both air and vacuum.
