Biodegradable materials, particularly metals (e.g., Mg, Zn, and Fe), are metals that are expected to corrode gradually in vivo, eliciting an appropriate host response from the release of corrosion products, and then dissolve completely after completing the mission of assisting tissue healing with no implant residues. Biodegradable metals have sparked a lot of interest in the field of biomedical implants due to their multiple advantages over non-biodegradable metals such as stainless steel and titanium-based alloys. These metal classes are desired due to their extraordinary physical and mechanical properties, such as an elastic modulus comparable to human bone, high specific strength, and low density. Magnesium alloys, in particular, have shown great potential for application in bone tissue repair. However, they are extremely prone to corrosion in the biological milieu, which could lead to the implants failing unexpectedly after a long period of usage. As a result, there is a need to slow down the observed deleterious effect, which might be accomplished through surface modification with safe inorganic coating materials. As a result, corrosion of magnesium alloys is a complex process that necessitates a thorough understanding of the many techniques used for full characterisation. In this fact-finding review, we would want to highlight the accomplishments and approaches used to monitor, enhance, and manufacture magnesium alloys intended to perform clinically with an appropriate host response.
