| Abstract Scope |
Biodegradable magnesium alloys are revolutionizing the field of biomedical implants by eliminating the need for secondary surgeries. Precipitation hardening plays a crucial role in enhancing the mechanical and corrosion properties of these magnesium alloys. This study examines the effect of precipitation hardening on the corrosion behavior of the Mg-6Zn-0.6Si-4Sn alloy in Hanks’ Balanced Salt Solution (HBSS). The pressure die cast alloy was subjected to solution treatment and further aged at 150 and 300 °C for 96 hours. The phase fraction, morphology and distribution of precipitates was calculated out using SEM and TEM. Mechanical properties were evaluated through hardness and compression testing, while corrosion was analysed using potentiodynamic polarization and weight loss measurements. Generally, the alloys aged at 150°C showed better mechanical and degradation properties than alloys aged at 300°C. The specimen peak-aged at 150°C produces fine nano-size, homogeneously distributed precipitates, which greatly increases strength and exhibits the best corrosion resistance. |
