|Abstract:||The present investigation aims to develop MoS2 added, self lubricated copper-tin hybrid composite with different weight fractions of MoS2 and characterize tribological properties. In order to evaluate the behavior of composites satisfying multiple performance measures, Taguchi approach has been adopted. An orthogonal array and an analysis of variance are employed to the influence of parameters like as wt% of MoS2, load, sliding speed and sliding distance on dry sliding wear of the composites. Results show that sliding distance has the highest influence followed by a load and reinforcement. Confirmation tests are carried out to verify the experimental results. The morphology of the worn-out surfaces is examined to understand the wear mechanisms. The responses have been predicted using both Artificial Neural Network (ANN) and Taguchi method so that a comparative evaluation can be made. From this study, it is concluded that neural network predicts the responses more accurately than Taguchi prediction.|
