Mathematical Modeling For The Prediction Of Wear Rate Of Al-12.6si/Tib2 In Situ Composites

In the present study, a mathematical model is proposed for the prediction of wear rate of Al-12.6Si alloy-based composites reinforced with in situ TiB2 (2, 3, 5 wt%) particles by halide salt reaction route. For deducing an empirical relationship for wear rate (pin-on-disc type wear), a multiple regression analysis has been performed to show its dependency on the TiB2 content of composite and various wear test parameters. From the regression statistics, it is inferred that the wear rate is strongly dependent on the rotating speed of the disc but moderately on the TiB2 content and applied normal load.
