Abstract: In the present investigation an attempt has been made to improve the tribological property of ZA-27 alloy by adding 1% Mn alloy. The wear behaviour of the modified ZA-27 alloy was studied by performing dry sliding wear test using pin-on-disc wear and friction monitor tester by varying Nr. Pressure and sliding speed. Experiments were conducted based on the plan of experiments generated through taguchi technique. An orthogonal array, signal-to-noise ratio and analysis of variance were employed to investigate the wear behaviour of modified ZA-27 alloy. The mathematical model was obtained to determine the wear rate of the modified ZA-27 alloy. The confirmation tests were conducted to verify the experimental results. In this study we found that the Nr. Pressure and sliding speed are more sensitive parameters.
