Abstract
Wear behavior of the HVOF deposited Cr3C2–NiCr and WC–Co coatings on Fe-base steels were evaluated by the pin-on-disc mechanism. The constant normal load applied to the pin was 49 N and sliding distance was 4500 m with velocity of 1 m/s, at ambient temperature and humidity. The specific wear rate of WC–Co coating was 3 mm3/N m and Cr3C2–NiCr coating was 5.3 mm3/N m. SEM/EDAX and XRD techniques were used to analyze the worn out surface and wear debris. The Fe2O3 was identified as the major phase in the wear debris. The wear mechanism is mild adhesive wear in nature.
