Corrosion in the Human Body
Metallic materials can find many kinds of applications in the human body: for example, in orthopaedics, for hip and knee prostheses, for osteosynthesis devices, in the cardiovascular sector, for endovascular prostheses, cardiac valves, pace-makers; in stomatological areas and for osteointegrated dental implants. Herein, some corrosion problems linked to the metallic materials used in the human body are examined, focusing in particular on orthopaedic materials. Failure mechanisms of these materials is briefly revised, dealing with fatigue, general and localised corrosion, fretting. Finally, a brief outline of the surface finishing treatments is presented.
