Magnesium (Mg) alloys have attractive properties as biodegradable implant materials for various applications including cardiovascular and orthopedic devices. For the electrochemical measurements, a three-electrode electrochemical cell was used, with saturated calomel electrode (SCE) as reference electrode and a platinum counter electrode. A shift of the EW62 RS Extrusion curve toward the upper left side of the diagram indicates an increase to more positive corrosion potential and a decrease in the corrosion current density. The improvement of nearly 40% in the corrosion rate of EW62 RS Extrusion alloy comes in line with the corrosion rate obtained by the immersion test. Based on the results obtained by this study, it is believed that the improved corrosion resistance of the proposed EW62 new alloy after rapid solidification and extrusion is related to the unique metallurgical characteristics of this material system.
