Wear Behavior of Zirconium Oxide (ZrO₂) Coating over the Surface of Electro Less Nickel Plating on Tool Steel Substrate

Abstract:

The knowledge of the properties of the coating in terms of wear resistance is of paramount importance in order to prevent the formation of severe damages. In this study, the wear performances of Zirconium oxide (ZrO₂) coating over the surface of electro less nickel plating on aluminum and tool steel substrate is analyzed. The surface morphology of coatings was examined by Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Spectroscopy (EDX) .The wear tests were performed in a pin on disc apparatus as per ASTM G-99 Standard. The coefficient of friction and wear loss are evaluated. The results of the wear test established that coated pins exhibited the lowest average coefficient of friction and the lowest wear loss when compared with uncoated pins.
