Abstract
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.
