Effect of Zn Additions on the Corrosion Resistance of Mg in Physiological Conditions

Abstract

Magnesium-based alloys are biodegradable and possess mechanical properties similar to bone, making them promising for orthopedic implants. Their controlled degradation eliminates the need for implant removal, reducing patient risk and healthcare costs. However, rapid biodegradation remains a challenge. Zinc, a biocompatible element, enhances osteogenesis, angiogenesis, and cellular adhesion, improving implant integration. This study aims to investigate the electrochemical behavior and corrosion resistance of three newly developed Mg-xZn alloys (x = 1.4, 4.1, and 6.1) when exposed to simulated body fluid, providing insights into their suitability for biomedical applications
