Abstract. The paper presents a relatively new solution of improving the tribological behavior of the steel-polycarbonate couple, by means of surface texturing via material removal. This solution consists of realizing a pattern of parallel grooves on the polycarbonate surface by aid of a laser beam. The effect of surface texturing upon both relative movement on contact area and surface wear is assessed experimentally.
