Notes:
Since adhesion plays a significant role in microtribology, properties of adhesion work ofseveral materials, such as Si, and mica are investigated by AFM. Experimental results indicate that,measured adhesion work varies with contacting velocity, surface roughness and so on, which is morethan a constant. Meanwhile, under invariable loads, friction force of these materials is also measuredover a wide range of velocity, which is found that adhesion work of the sample surface directlyinfluences the velocity dependent property of micro friction force. This makes the observed microfrictional behaviour significantly differs from the traditional macro friction laws, in which frictionforce is proved be independent of sliding velocity. Additionally, with zero or negative load, frictionforces are proved to be determined by adhesion work and adhesion contact area. Finally, arelationship between micro friction force and adhesion work is outlined
