Title (EN) DESIGNED SURFACES FOR USE IN MEDICAL IMPLANTS OR INSTRUMENTS
(FR) SURFACES FAÇONNÉES À UTILISER DANS DES IMPLANTS OU DES INSTRUMENTS MÉDICAUX
Abstract:
(EN) A medical implant device or component thereof comprising a metal substrate and a coating layer structure provided on the substrate. The coating layer structure comprises an outermost layer of a ceramic material. A bonding structure is deposited between the metal substrate and the coating layer structure. The bonding structure comprises a chromium rich layer, which is deposited onto the metal substrate surface and has a higher concentration of chromium than the metal substrate, as well as a gradient layer having a composition gradient from the chromium rich layer towards the surface of the device providing increasing proportions of a gradient material which has structural correspondence with the layer of the coating layer structure that is most adjacent to the bonding structure.
(FR) La présente invention concerne un implant médical ou un composant de celui-ci comprenant un substrat métallique et une structure de couches de revêtement sur ce substrat. Cette structure de couches de revêtement comprend une couche externe en matériau céramique. Une structure de liaison est déposée entre le substrat métallique et la structure de couches de revêtement. Cette structure de liaison comprend une couche riche en chrome déposée sur la surface du substrat métallique et dont la concentration en chrome est supérieure à celle du substrat métallique, ainsi qu'une couche de gradient présentant un gradient de composition depuis la couche riche en chrome vers la surface de l'implant et fournissant des proportions accrues d'un matériau à gradient qui correspond au niveau structural à la couche de la structure de couches de revêtement la plus proche de la structure de liaison.
