The aim of this work is to fabricate aluminum, boron carbide (B4C) based aluminum matrix composites (AMCs) using easyand cost effective powder metallurgy (P/M) route. Here, Al?Mg?Si composites having different weight fractions of B4C(3.5,7.0,10.5,14.0 and 17.5 wt%) were synthesized to study the dry sliding wear behavior with respect to automobile brakepad material. The surface morphology and elemental composition of fabricated composite material were characterized byScanning Electron Microscope (SEM) and energy dispersive x-ray spectroscopy (EDS) respectively. Further, dry sliding weartests were conducted with respect to i.e. applied loads, sliding distances and reinforcements for the performance analysis ofsynthesized AMCs. A linear regression model was used to optimize the control factors. Furthermore, explore the effects ofreinforcements on density, Vickers hardness, wear rate and worn out surface morphology. Further, the analysis also revealedthe critical wear mechanisms with their wear debris for improvement in the AMCs. The hardness of aluminum composite(17.5% B4C/Al?Mg?Si) showed 54.15% higher value than matrix alloy. Furthermore, it was observed that AMCs showedsignificant improvement on the various factors e.g., applied load (L), sliding distances (SD) and reinforcements (R) thanthat of aluminium matrix alloy.
