In this work, Mg and Zn powder were used to prepare the Mg-Zn/β-TCP composites with different β-TCP composition by using powder metallurgy technique. The composite were mixed using ball mill and compacted at 500 MPa. The composites sintered at 450 °C in tube furnace for two hours. The effects of properties on Mg-Zn with different composition of β-TCP were studied. The results on the effect of β-TCP composition were analyzed in terms of density and microstructural analysis.
This paper presents the corrosion behavior of the composite Mg-10wt.% bio-glass (45S5) with different concentration of Zn. Bio-glass (BG) was added to the composite in order to improve bioactivity behavior of magnesium. The composite was fabricated by mixing, compacting followed by sintering. Composites was compacted at 550 MPa and sintered at 450°C under an argon atmosphere. Corrosion behavior was investigated by the immersion test. Sintered samples were immersed in 0.9 % NaCI solution and monitored by hydrogen evolution and XRD analysis. The results showed that hydrogen evolution rate decreased with addition of Zn content. The microstructure and phase analysis were observed by optical microscope, scanning electron microscope and x-ray diffraction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
