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.
