Influence of the surface texturing of non-conformal surfaces at the friction coefficient
 Pišťáček, Karel ; Náhlík, Luboš (referee) ; Koutný, Daniel (advisor)
This diploma thesis deals with the influence of the surface texturing of non-conformal surfaces at the friction coefficient. In the work were made adjustment of experimental apparatus for measuring friction in the contact between ball and flat disk. Friction coefficient was calculated by the size of the torque on the ball, which was measured by the torque sensor. For recording and processing signal from the sensor was designed software that makes it possible to measure the coefficient of friction for selected conditions (loading of contact, speed of rubbing surfaces and rolling-sliding conditions). Experiments were carried out with smooth and textured ball, glass, and steel disc at different speeds and rolling-sliding conditions. To determine the effect of the influence of the surface texturing at the friction coefficient the size of the coefficient of friction of smooth and textured ball was compared. It was found that the microtexture of the friction coefficient has little effect.
