The objective of the paper mainly discusses on effects of coating each one of the below materials namely TiAlN, ZrAlN and ZrN + Al2O3 on ZA-27 alloy specimens to understand wear resistance characteristics of such coated composite by cathodic arc coating techniques, also investigation was made on their composition, structure, hardness and wear behaviour at constant coating thickness using profilometer, EDX, SEM and pin on disc, respectively, at room temperature. The hardness of the ZrN + Al2O3, TiAlN and ZrAlN are 29.06 GPa, 24.49 GPa and 22.06 GPa, respectively, and the microstructure reveals that ZrN + Al2O3 exhibited outstanding properties compared to other two because of columnar structure, dense grain size and multilayer coatings. Also, ZrN + Al2O3 exhibited superior wear resistance than TiAlN and ZrAlN due to the Al2O3 layer present on the upper layer of ZrN which prevents the effect of oxidation and reduces friction between tool and work piece.
