Prostheses with controlled degradation rate
(PHYSorg.com Chemistry)

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.
