Since magnesium alloys are degradable, they could provide an alternative to the metals traditionally used as prostheses, connecting parts to heal bones or as stents for cardiovascular problems. A study by the UPV/EHU Faculty of Engineering in Bilbao has made progress on one of the weak points of the new material. Its degradation rate has been adjusted by applying a calcium phosphate coating to the surface via electrodeposition, and the thickness of the layer has been accurately adjusted.
