What is Wear characteristics of Cr3C2–NiCr and WC–Co coatings deposited by LPG fueled HVOF about?

Wear behavior of the HVOF deposited Cr 3 C 2 -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 mm 3 /N m and Cr 3 C 2 -NiCr coating was 5.3 mm 3 /N m. SEM/EDAX and XRD techniques were used to analyze the worn out surface and wear debris. The Fe 2 O 3 was identified as the major phase in the wear debris. The wear mechanism is mild adhesive wear in nature.
