Materials with unusual and challenging combinations of properties like low density, good strength, high stiffness along with abrasion, impact and corrosion resistance, which cannot be experienced by the conventional materials are required in many of our modern technologies needed for aerospace, underwater and transportation applications. Al-Si Alloy has been proved to be an excellent material to substitute conventional engineering materials by virtue of its good castability, corrosion resistance and specific strength. Nevertheless, in-situ TiB2 reinforcement adds to its wear properties because of its outstanding hardness and clean interface during formation. In the present study, an effort has been made to synthesize Al-Si alloys reinforced with TiB2 particles through salt metal reaction and to highlight the performance of these composites with respect to variation in silicon content accompanied by TiB2particles synthesised by stir casting method. A pin-on-disc wear testing machine has been used to investigate the dry sliding wear behaviour of these composites with varying load (10, 20, 30) N and varying speed (300, 400, 500) rpm. Microstructural characterization by Scanning Electron Microscope and optical microscope clearly explained the enhanced wear properties of the composites attributed to the variation of Si content and presence of TiB2 which alters the morphology and distribution of various phases.
