The Role of Antibacterial Metallic Elements in Simultaneously Improving the Corrosion Resistance and Antibacterial Activity of Magnesium Alloys

Magnesium-based biodegradable alloys exhibit excellent mechanical properties and bioactivity, which are favorable in the orthopedic applications. In addition, the degradation of Mg alloys results in an alkaline microenvironment which can effectively withstand bacteria. However, the degradation rate of Mg is too fast to sustain the healing process. And enhancement of its corrosion resistance may compromise the antibacterial ability, thus,...
