Research on bone regeneration has always been an intense and challenging field of tissue engineering. Biodegradable metals represent a novel class biomaterials combining superior mechanical qualities with capacity to promote growth. Among them, magnesium (Mg) its alloys have proposed as innovative for grafting therapy due their non-toxic nature comparable properties bones. In addition, they are lightweight, biocompatible biodegradable. They offer several advantages over other implant metals, including reduced stress-shielding effects unnecessity second surgery remove them. Unfortunately, clinical application is limited the rapid degradation rates in rather aggressive physiological conditions. Therefore, development Mg-based implants possessing controlled accordance kinetics healing necessary. On hand, protective yet biodegradable surface coatings emerged useful strategy fulfill diverse requirements, effective corrosion resistance. Calcium orthophosphates (abbreviated CaPO4) excellent candidates producing such well tolerated by living organisms. However, high chemical reactivity low melting point, grafts require specific parameters successful CaPO4 deposition. This paper reviews currently available preparation methods deposits Mg alloys, aiming build up comprehensive knowledge framework deposition techniques, processing parameters, performance measures terms resistance, adhesion strength biocompatibility. The literature analysis shows that increase ability magnesium-based metallic withstand improve biocompatibility surfaces all cases.
