Elaboration de couches minces de carbone par ablation laser femtoseconde pour application aux biomatériaux implantables

Abstract : This work is devoted to the elaboration of DLC (Diamond-Like Carbon) thin films by femtosecond pulsed laser deposition (PLD) for a biomedical application : hip joints. The structure, the mechanical and tribological properties of the films have been characterized and a femoral head of hip joint has been coated. This report is divided in four parts :
the first part is devoted to a presentation of the carbon thin films properties , a literature study of some deposition techniques and the potential or recognized applications of the deposited layers. The second chapter describes the experimental devices used for thin films deposition and the different characterizations. The chapter 3 presents the structure, the mechanical and tribological properties of deposited carbon thin films. The capacity of these ta-C films (tetrahedral amorphous-Carbon) to satisfy the biomedical requirements is confirmed. The last chapter is related to the coating of 22.2 mm diameter femoral head of hip joint. In situ sputter cleaning prior to deposition has been performed to enhance the adhesion of the films on biomedical metallic substrates.
