Abstract: Electrospark coating, or in other words electrospark alloying, is well known surface modification technology to improve the properties of metallic surfaces. Electrospark coating process can be described as micro welding and as electrodes (anodes) for such micro welding can be used any electric conductor, i.e. metals or its alloys, hard metals. The unique microstructure and properties can be created through electrospark alloying. Good resistance to wear can be achieved using high carbon steels, WC-Co, Ti-Co or other alloys as anode. Only relatively thin coating layers (0.01...0.5mm) and high roughness restrict the usage of electrospark coatings in some areas. The wear resistance of Ti15-Co6 is presented in this paper when wear test was performed in two different conditions. First, friction pier was pin-on-disc, both surfaces were coated. And second, abrasive wear test. Research results show that more useful tribo-pair is when working surfaces are both coated with Ti15-Co6 alloy
