Abstracts: The tribological properties of a series of aluminium-Silicon alloys developed for machinery parts included for aerospace and automotive applications were evaluated. This thesis encompasses the chemical composition of this aluminium alloy and the assessment of their tribological response when subjected to Pin-on-Disc wear test, which was performed on lathe machine. The EN31 steel disc was directly fitted on to the spindle of geared based lathe machine and varying the spindle speed. And the Pin of utectic aluminium alloy was fitted on to the tool post with the help of lathe tool dynamometer attachment, which indicated the load in terms of kg. An attempt has been made to study the influence of wear parameters like sliding speed in rpm (125,375,500), time in second (300,600,900), and radial contacting surface area or wear track at diameter (100,120,140) on the sliding wear of the Aluminium alloys up to 1 kg loads. A plan of experiments, based on the techniques of Taguchi, was performed to acquire data in controlled way. An orthogonal array and the analysis of variance (ANOVA) were employed to investigate the wear behavior. The wear tests were measured with great accuracy 0.1 mg by before weight and after weight of pin material. The analysis of variance (ANOVA) result shows that theoretically and experiment.
