Influence of ti o2 and sn particles on the mechanical tribological characteristics and degradation of magnesium metal matrix composites

Abstract

Magnesium and its alloys have the potential for use in implants newlinedue to their low toxicity and similarities to natural bone in terms of newlinestrength. However, their susceptibility to oxidation and low wear newlineresistance has limited their applications. Magnesium-based metal matrix newlinecomposites (Mg-MMCs) offer a solution, as they combine the lightweight newlineproperties of magnesium with enhanced mechanical and corrosion newlinecharacteristics. In biomedical applications, specific magnesium alloys and newlineMg-MMCs with non-toxic alloying elements are being explored for newlinevarious applications, showing promise in enhancing implant materials. newlineThis comprehensive study explores the mechanical, tribological, and newlinedegradation characteristics of magnesium-based metal matrix composites newline(Mg-MMCs) reinforced with Titanium dioxide (TiO2) nanoparticles (0.5, newline1.5 and 2.5 wt.%) and the AZ31/1.5 wt.% TiO2 composites further newlinereinforced with Tin (Sn) microparticles (3, 6, 9, and 12 wt.%) using bottom newlinepouring stir casting technique. newline
