In recent years, traditional metallic biomaterials including pure Ti and its alloys, CoCr alloys, and stainless steel have been widely applied into bone replacement and bone fixation devices in order to repair bone fractures or support in the healing process. However, these types of traditional metallic biomaterials required secondary surgery in order to remove the implants after healing.
Magnesium and its alloys appeared as promising candidates for biodegradable implant applications that do not require additional surgery for the removal of the implant after healing. The most significant challenge with Mg-based alloys is the high corrosion rate of Mg and maintain their mechanical properties during the healing period.
Carefully selected alloying elements with a favorable metalworking process is the crucial aspect for enhancing and control the corrosion properties of magnesium alloys. Attention will be paid to magnesium alloys prepared by different metalworking processes.
