Microstructure and Compressive Strength of Magnesium-Zinc Alloy Reinforced with Different Percentage of Bio-Glass Content

Abstract:

The objective of this work is to fabricate composite Mg-Zn filled with 45S5 bio-glass (5, 10, and 15 wt. %) via powder metallurgy. The microstructure of the sintered composite was investigated using optical microscope and scanning electron microscope. The densities of the composites were also evaluated. The densities of the compacts are increasing with increasing bio-glass content. Compression test was done by the Instron machine. The result showed that bio-glass was dispersed in the Mg-Zn matrix. Compressive strength was decreased as the amount of bio-glass increased. However, the results are still comparable to natural bone, which is important to reduce the stress shielding effect.
