Abstract: The present study deals with investigation relating to the influence of wear parameters like sliding speed, applied load and sliding distance on the sliding wear of aluminium silicon titanium alloys under lubrication condition. The design of experiment approach was employed to acquire data in controlled way using Taguchi method. A pin-on-disc apparatus was used to conduct the sliding wear test under lubrication condition. An orthogonal array, signal-to-noise ratio and analysis of variance were employed to investigate the wear behavior of aluminium and itís alloys. The mathematical model was obtained to determine the wear rate of the aluminium and itís alloys. Addition of titanium in aluminium silicon alloys modifies microstructure as well improves the tribological characteristics.
