A prosthetic device having at least part of its surface comprising a diffusion- hardened, in-situ formed oxidation or nitridation layer and with at least another part of its surface comprising a coating of bioceramic, preferably hydroxyapatite. The bone in-growth and on-growth promoting bioceramic further works synergistically with the diffusion-hardened surface in realizing a longer service life prosthetic.
L'invention concerne un dispositif de prothèse dont au moins une partie de la surface est durcie par diffusion, comprend une couche de nitruration ou d'oxydation formée in situ, et dont au moins une autre partie de la surface comporte un revêtement de biocéramique, de préférence de l'hydroxyapatite. La biocéramique favorisant la croissance osseuse interne et externe présente aussi une synergie avec la surface durcie par diffusion donnant une prothèse à durée de service plus importante.
