Measurement of friction force on solid surface with micro tip

Abstract

The direct measurement of interaction force between two solid surfaces is capable by using Friction Force Microscope (FFM). The friction force between both surfaces of a silicon tip and a smooth silicon flat are measured, using the Frictional Curve (FC). The friction curve was measured by varying the normal load within a range of 100nN or less. The result showed that it is found by measuring the frictional curve that the frictional force changes depending on the normal load and the frictional force was larger than the macroscopic frictional force. And influence of relative humidity on micro tip adsorption is investigated.
