| 摘 要： | With the development of nanoscience, micro/nano tri-bology is becoming very important in many systems such as microelectromechanical systems and magnetic re-cording devices1,2]. Atomic force microscope (AFM) and friction force microscope (FFM) have been proven to be powerful tools for studying micro/nanotribology3―5]. At nanoscale, it is doubtful whether the friction force is independent of the sliding velocity or not, because re-ported experimental results are contradictory. Zhang 6] an…

| Abstract: | 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 surface 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 significantly, and the friction force is much smaller than that in air. |
