In the last few years, magnesium (Mg) and its alloys have attracted much attention as a promising candidate for degradable implant appliions such as bone-fixation plates, screws, wires, pins
weight ratio. At present time, magnesium alloys are com-monly used in the automotive industry, but their biocom-patibility and biodegrability also provide possibilities for biomedical appliions, such as e.g. degradable stents or bone fracture xation pins [1 5]. orF
Zinc is commonly used as an alloying element for magnesium alloys, and the yield strength of magnesium alloys increase with its zinc content []. Magnesium alloys are especially important for orthopedic appliions as it contains a Young’s modulus with a value of 3–20 GPa, which is very similar to the Young’s modulus for bone 20 GPa [ 55 ].
