Biocéramiques: des monolithes aux composites

Abstract : This document presents a synthesis of my research activities about bioceramics. It is conceived as a state of the art on biomedical ceramics, and divided into two independent parts. Part A deals with bio-inert ceramics used for orthopaedic applications (hip or knee prostheses...). This part tries to be exhaustive on biomedical zirconia, from purely "material aspects" (phase transformation, toughening mechanisms...) to functional properties (lifetime, degradation mechanisms...). This part is concluded by some aspects of "future" ceramics and composites for orthopaedics: alumina-zirconia composites, ceria- or magnesia-doped zirconia... Part B deals with bio-active ceramics, mostly used for bone substitution. Since these materials are very fragile, I propose solutions to improve their mechanical properties. Solutions based on bioactive glass-ceramics and porous fuctionaly graded materials are exposed.
