| Abstract Scope |
Magnesium-based biodegradable composites own specific attributes and are suitable for orthopedic applications. Despite this, corrosion characteristic is the crucial factor. This work fabricated magnesium/nano-HA biodegradable nanocomposites through microwave sintering. These nanocomposites were characterised and observed higher densification in lower nano-HA percentage composite. Electrochemical corrosion results show that nano-HA particles lead higher corrosion rate, The reason for this may be the agglomeration of nano-HA reinforcement. The outcomes of the EIS study also depict similar results in terms of impedance and phase angle. Moreover, in-vitro biocorrosion tests were performed in human body salt solution and noticed that the nano-composites experienced corrosion-protective passive layers, which led to reduced corrosion from the surface. However, immersion test results explain biocorrosion kinetics and behavior of nano-composites in real working conditions. The results show that microwave sintered composites can be used as a substitute material for biodegradable implants, which are widely used for healing malfunctioned tissues. |
