It is well known that the tribological performance of materials highly depends on the surface topography. An experimental research to determine the friction coefficients for a few couples of material such as microtextured silicon/stainless steel, aluminium, copper, FR4 (epoxy-glass laminate) and PVC (Polyvinyl Chloride) is presented in this paper. (100) oriented monocrystalline silicon, microtextured through MEMS (Microelectromechanical Systems) technologies, was used. The influence of surface roughness on the static friction coefficient has been studied also. The experimental results have been validated by simulation with 20-sim software.
