Magnesium has been known as an appropriate biological material on account of its good biocompatibility and biodegradability properties in addition to advantageous mechanical properties. Mg and its alloys are of poor corrosion resistance. Its high corrosion rate leads to its quick decomposition in the corrosive ambiance and as a result weakening its mechanical properties and before it is repaired, it will vanish. The corrosion and degradation rate must be controlled in the body to advance the usage of Mg and its alloys as implants. Different techniques have been utilized to boost biological properties.
