Fuzzy Logic Investigations on Wear Analysis of P/M-Produced Aluminum Composite Through Non-lubricated Mode

The metal matrix composites (MMCs) are most suitable replacements not only in the steel materials but also in the aluminum alloys in various automobile and aerospace systems and components. The present research fabricated novel aluminum-based MMCs which has undergone with dry sliding or non-lubricated tests to verify the wear characteristics of the composite. The study reveals the non-lubricated wear behavior of the composites at the sliding speed of 1.5 m/s and the loads of (15, 25, 35, and 45) N under normal ambient condition by using a pin-on-disk tribometer. The results shown the wear rate of the composite is much lower than that of the matrix alloy and also decreases with increasing of SiC content. Further, the experimental values have applied to fuzzy model with percentages of SiC where the applied loads were taken as inputs and the wear rate as the output. The output of the developed fuzzy model was compared with experimentally obtained results, and the deviation is declared to be within 3.0%.
