Introduction to Metallic Biomaterials

Résumé

The paper presents a bibliographic study about the metallic biomaterials, synthesizing the aspects related to properties, applicability, obtaining methods. Biomaterials can be used as medical devices, implants and prostheses. The metallic biomaterials are classified, by chemical composition and structure, in: pure technical metals, metallic alloys and composites with metallic matrix. The material quality of an implant must respect the following criteria: biochemical criteria and biomechanical ones. According to the biochemical criterion, the applicability of a material is determined by its biocompatibility, and from the biochemical criteria, it is determined by the fatigue resistance, the most important parameter, but not the only one.
