Metallic materials like stainless steel, Co-based and Ti alloys are being used as biomedical implants. The problem of stress shielding and metal ion releases exhibits with these metals, which affects biocompatibility and corrosion behaviour of implants. Also, the secondary removal surgery is one of the biggest reasons behind the exposure of the body to the toxic contents. This leads to the development of biodegradable metallic biomaterials which eliminates secondary surgery to remove the implant. Magnesium (Mg) as a trace element of human body possesses excellent properties to be a biodegradable medical implant like low density and young’s modulus, good biocompatibility and Osseo-integration, also it is non-toxic in body fluids. Magnesium alloys also having good mechanical properties reliable to bear body loads. In this review, the effects of alloying elements and surface treatment such as coating on corrosion behaviour of Mg alloys are summarized which describes the degradation rate and biocompatibility. This study reveals that the degradation rate can be controlled by reducing the corrosion rate with the help of proper alloying and surface coatings and the biocompatibility can be improved as well.
