Meso-scale mapping of friction force distribution

Abstract

This paper describes development of a low-load tribo-tester in order to obtain meso-scale mapping of friction force. Sliding experiment was carried out with Al_2O_3 and Diamond slider. The condition of sliding test were 0.5mm/s of sliding speed and 4.9∿9.8mN of load. From the experimental results, we were obtained meso-scale mapping of friction coefficient. Spatial resolution of mapping was dependent on curvature radius of slider surface. In the case of Diamond slider, the spatial resolution was about 10μm.
