The Aluminum metal matrix nanocomposites have attracted pronounced attention for marine, aerospace and automotive applications since their high hardness and wear resistance ability. In this work, a metal matrix nanocomposite composed of Titanium dioxide (TiO2) and Magnesium oxide (MgO) nanofillers of ceramics with Aluminum (Al) matrix were prepared by powder metallurgy route. Field Emission Scanning Electron Microscope (FESEM), X-ray diffraction (XRD), Brinell hardness and optical microscopy were provided the role of the surface modifications, interfacial region, microstructure properties and characterizations, and the significance of controlling the nanofiller surface for improving the mechanical properties. It was observed that the interface effect between the Aluminuim matrix and nanofillers enhances the hardness and wear resistance in the nanocomposite. Wear test was carried out by changing applied loads as 2,4,6,8 and 10 N and time as 3,6,9,12 and 15 min. The result of this work revealed that improving the hardness and wear resistance for MgO nanoparticles more than TiO2 nanoparticles. While the SEM examination reveals that homogenous distribution of nano MgO particles & TiO2 nano particles in aluminum matrix with an amount of porosity. The obtained results are auspicious for high-performance functional materials operating at high temperatures satisfying various requirements for emerging applications
