Abstract:

<p>The aim of this research is to fabricate functionally graded aluminium composite reinforced with 15 wt% alumina using centrifugal casting technique with dimensions of Øout160 x Øin145 x 150 mm and to investigate its three-body abrasive wear behavior. Hardness tests and microstructural examinations were performed at distances of 2, 8 and 14 mm from outer diameter. Based on hardness test results, wear tests were carried out at a distance of 2 mm from outer diameter and a total of 16 experiments were conducted as per Taguchi’s Design of Experiments. The parameters varied were load applied on the specimen (29, 34, 41 and 53 N), sliding speed at the surface of the specimen (75, 100, 125 and 150 rpm) and time of operation (3, 5, 7 and 9 mins) and their influence on the wear rate was analyzed using Analysis of Variance and Signal-to-Noise ratio. The most dominating parameter was found out to be the load applied and subsequently a regression equation was generated. Finally, the worn surfaces were analyzed using Scanning Electron Microscope. The images obtained were used to explain the wear mechanisms and it was found out that increased load caused severe ploughing action on the surface. This indicates that the load applied on the component fabricated with this material is the major factor in determining is life. © School of Engineering, Taylor’s University.</p>
