The presented work provides the results of the abrasive wear resistance tests performed on Co-Cr-Mo and Co-Cr-Mo-W alloys with the use of the Miller’s apparatus. The analyzed alloys underwent microstructure observations as well as hardness measurements, and the abraded surfaces of the examined materials were observed by means of electron scanning microscopy. The performed examinations made it possible to state that the Co-Cr alloys characterized in a high hardness, whereas the changes in the mass decrement were minimal, which proved a high abrasive wear resistance.

W prezentowanej pracy przedstawiono wyniki badań zużycia ściernego stopów, Co-Cr-Mo i Co-Cr-Mo-W przy użyciu aparatu Millera. Analizowane stopy poddano obserwacjom mikrostruktury, pomiarom twardości i mikrotwardości, a ścierane powierzchnie badanych materiałów obserwacji przy wykorzystaniu elektronowej mikroskopii skaningowej. Przeprowadzone badania pozwoliły na stwierdzenie, że stopy, Co-Cr charakteryzowały się wysoką twardością i mikrotwardością, zaś zmiany ubytku masy były bardzo minimalne, co świadczy o wysokiej odporności na ścieranie.
