MWCNTs-TiO2 incorporated-Mg composites to improve the mechanical, corrosion and biological characteristics for use in biomedical fields

This study attempts to synthesize MgZn/TiO2-MWCNTs composites with varying TiO2-MWCNT concentrations using mechanical alloying and a semi-powder metallurgy process coupled with spark plasma sintering. It also aims to investigate the mechanical, corrosion, and antibacterial properties of these compos...
