Abstract :
The paper presents the results of a scientific research using an original experimental setup dedicated for studying the influence of surface material and topography on tribological behavior. The experimental setup is provided with a safety clutch with two steel disks. On the frictional disk, permanently maintained, a ferodo ring is bonded. The other disk, with the material to be tested, was changed each time. Silicon microtextured wafers and chromium (non)textured thin layers deposited on silicon wafers were tested. The size and shape of the depressions were varied and their influence on the friction coefficient was studied. The angular speed of driver and driven shaft was measured with two non contact tachometers.
