Abstract in different language:	Superalloys with cobalt as a base material are widely used among different industry applications. Their main advantages are excellent corrosion and wear resistance. Material CoCrTaAlCSiY was chosen for this study as an unexplored representative of Co-based superalloys with a potential for good tribological behavior. This paper follows the results of previous paper called “Microstructure and Tribological Behavior of HVOF Sprayed and Laser Remelted CoCrTaAlCSiY Coatings”. In this paper are also presented three states of HVOF sprayed and post laser treated coatings of CoCrTaAlCSiY (as spray state and two different laser treatments varying in specific energy of laser). Pin-on-disc test was carried out to evaluate wear behavior. XRD analysis was done to reveal phase transformations between FCC and HCP. A positive effect on wear coefficient for both laser treated CoCrTaAlCSiY coatings was proved.
