In this work, a monotectoid based Zinc–Aluminium (Zn–Al) alloy was prepared using stir casting process. The Micro-Hardness of as-cast and homogenized conditions was tested and the result showed that the homogenized alloy has a slight improvement in hardness than that of the as-cast alloy. The Microstructure of the Zn–Al revealed the dendritic structure in as-cast and non-dendritic in homogenized conditions which were analysed through a scanning electron microscope (SEM). Adhesive wear is carried out by Pin-on-Disc wear tester. Wear rate of the alloy rises with applied load conducted at different speeds. The specific wear rate and the friction coefficient vary with load. The diffusion of disc material into the specimen material changes the alloy composition. It was observed through energy dispersive X-ray spectroscopy (EDX) analysis. The worn-out surfaces were studied by using SEM analysis. © 2019, Springer Nature Singapore Pte Ltd.
