In Vitro Electrochemical Corrosion Assessment of Magnesium Nanocomposites Reinforced with Samarium(III) Oxide and Silicon Dioxide Nanoparticles

Recent research on biodegradable magnesium-based implants has been focusing increasing their mechanical strength and controlling corrosion rate. One promising approach to significantly improve the properties of magnesium is addition nanoparticles matrix. However, there limited behavior these new nanocomposites. In this study, electrochemical characteristics class biomaterials are investigated. Two nanocomposites reinforced with (0.5, 1.0, 1.5 Vol%) samarium oxide (Sm2O3), silicon dioxide (SiO2), were fabricated tested. Corrosion was assessed in comparison high-purity samples as control group. The matrix strengthened materials, which represented an increase microhardness. nanocomposite exhibited a slightly reduced resistance compared due differences purity level fabrication methods. Both showed highest resistance, slowest rates, at 1.0 Vol% content. Hence, developed still candidates materials for bone-fixation application owing superior acceptable characteristics.
