The present investigation aims to evaluate the wear behaviour of Nickel aluminide (Ni3Al) coated on zinc-aluminium (ZA-12) alloy composites by thermal evaporation process. A pin-on disc wear testing machine is used to evaluate the wear loss of alloy. In recent years Ni3Al has attracted considerable interest due to their inherent properties such as withstanding high temperature etc. Further coating on ZA-12 provides good physical strength and tribological properties to ensure less wear of the material. In this paper an attempt has been made to provide an extensive performance ofNi3Alcoated on ZA-12 to analyze the performance of the material in bush bearing of automobiles to prevent friction and wear of bearing parts.

Keywords: Ni3Al, ZA-12, Friction, Wear
