Abstract
Abstract The present work studies the lightweight Hybrid Aluminium Metal Matrix Nanocomposite (HAMNC) for brake rotor application. The novel HAMNC brake rotor material is fabricated by reinforcing 1 wt. % nano Boron carbide (nB4C) and 0.75 wt.% nano Titanium dioxide (nTiO2) employing ultrasonic-squeeze-assisted stir-casting process. The developed HAMNC and a commercial Gray Cast Iron (GCI) brake rotor material was subjected to density, hardness, thermal, corrosion, and tribological studies. The results indicated that the HAMNC brake rotor material is 60% lighter and extremely corrosive resistant compared with GCI material. Also, the dry sliding wear study done using Non Asbestos Organic (NAO) commercial brake pad as the pin material exhibited that the HAMNC brake rotor material possessed a higher wear-resistant behavior compared to GCI.
