The paper deals with the laboratory investigation of tribological properties of selective laser-sintered and laser coated parts. The investigations were made in connection with using of laser-sintered prototype tools for injection molding of plastics. These tools should be able for the production of small badges. On a pin-on-ring machine we investigated the friction and wear properties of uncoated parts. In the next etap of our investigations we focused on edges and inlets where wear is more severe, and therefore improvement of the surface by coating is required. We produced Mogul and FeB surfaces by laser alloying on the sintered work pieces and we tested them on special cylinder-on-cylinder tribometer against high performance plastics. It was found, that the coated specimens had better wear resistance characteristics and slightly lower coefficient of friction.
