Abstrakt: In this study, magnesium (Mg)-based nanocomposites reinforced with silica (SiO 2 ) nanoparticles were developed using the powder metallurgy process, and their mechanical and corrosion behavior were assessed. Mg-alloy AZ31 served as the matrix material, and two different weight percentages of SiO 2 nanoparticles were used as filler. According to the microstructural analysis, the composite generated a Mg 2 Si phase as a result of SiO 2 dissociating during the sintering process. The microhardness of the Mg-alloy dramatically enhanced with the addition of 3% nanosilica, although the elastic modulus remained constant. Additionally, the outcomes demonstrated that the Mg 2 Si phase's development in the composite constrained the mechanism of deterioration and postponed the pace of degradation, which aided in enhancing the qualities of corrosion resistance. This nanocomposite might, thus, be thought of as a potential replacement for the traditional bio-implant materials.
