Biomaterials Surface Integrity

Résumé

Nowadays prostheses intended for biomedical use are manufactured by various processes such as machining, 3D printing, molding, forging. All these manufacturing processes generate a characteristic “imprint” on the prosthesis shape called surface integrity. The concept of surface integrity represents a new and preferential approach to characterize the biomaterials surface and subsurface properties regard to the functional requirement of prosthesis. Surface integrity analysis provides a comprehensive evaluation of the surface and its impact on the performance of the prosthesis. The concept of surface integrity is made up several components such as roughness, dislocations, porosity, electrical conductivity, wettability. However, the integrity of the surface obtained, which must be suitable to meet expected clinical requirements is influenced by the manufacturing process parameters used. To assess surface integrity, a lot of characterization techniques are available depending on the observation scales including, but not limited to spectroscopy, optical imaging methods, nanoindentation, magnetic property measurements, roughness measurements, and X-Ray inspection.
