Mechanical Properties and Corrosion Behavior of Silica Nanoparticle Reinforced Magnesium Nanocomposite for Bio-Implant Application.

In this study, magnesium (Mg)-based nanocomposites reinforced with silica (SiO) 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 nanoparticles were used as filler. According to the microstructural analysis, the composite generated a MgSi phase as a result of SiO dissociating during the sintering process.
