This contemporary work has mainly engrossed on optimization of wear loss of modified zinc aluminium (ZA- 27) alloy with varying inputs like sliding speed, normal load, and sliding distance were used to conduct dry sliding wear experiments on a friction and wear testing equipment. The experiments were designed using a Taguchi mixed design L16 (4^2 ^1) orthogonal array. The impacts of wear feature (input) on wear loss (output) of ZA-27 alloy were deliberated using Taguchi and ANOVA. Best parameters for minimum wear loss are a normal load of 9.81N, a sliding speed of 2 m/s, and a sliding distance of 2500m, according to the findings. The contributions of sliding distance, sliding speed and normal load were 0.07%, 6.01% and 81.48%, respectively, according to ANOVA. For the modified ZA-27 alloy, Taguchi and ANOVA results reveal the same influence order. At higher loads and speeds, the worn surface reveals that the sub-surfaces fractured and broken, forming a platelike structure of wear debris.
