Since adhesion plays a significant role in microtribology, properties of adhesion work of several materials, such as Si, and mica are investigated by AFM.
In order to examine the variable properties of adhesion work between two surfaces, several materials are prepared in our tests, such as Si(100), and newly cleaved mica.
Furthermore, our experiments also show that adhesion forces are independent of the maximum contact load, since the pull-off forces on all the tested materials keep constant when load varies from nNs to µNs.
For the tested materials, adhesion work directly influences the velocity dependent property of micro friction force.
