Nickel-Free Alloy Implant – Chronifer 108<\/h1><\/div>

L’acier inoxydable utilis\u00e9 pour les implants doit \u00eatre r\u00e9sistant \u00e0 la corrosion et biocompatible. Comme les implants sont toujours plac\u00e9s dans le corps, il est indispensable de viser une haute tol\u00e9rance biologique lors du choix du mat\u00e9riau.<\/p>\n

La plupart du temps, ces implants sont en alliage chrome-cobalt-molybd\u00e8ne, en acier aust\u00e9nitique ou en titane. Ce dernier est surtout utilis\u00e9 chez les patients souffrant d’une allergie de contact (au chrome et au nickel).<\/p>\n

L’acier CHRONIFER 108 de la maison est un acier inoxydable aust\u00e9nitique sans nickel. Il est exempt de ferrite \u2202 (delta), non magn\u00e9tique et convient bien \u00e0 toutes les applications qui exigent \u00e0 la fois une grande solidit\u00e9 et une bonne r\u00e9sistance \u00e0 la corrosion. Ces propri\u00e9t\u00e9s rendent cet acier particuli\u00e8rement attrayant pour les implants et les proth\u00e8ses de remplacement des articulations.<\/p>\n<\/div><\/div><\/div>

Caract\u00e9ristiques et particularit\u00e9s<\/strong><\/p>\n

L\u2019acier CHRONIFER 108 est l\u2019acier aust\u00e9nitique sans nickel \u201cBioDur\u00ae 108 Alloy\u201c de Carpenter. La substitution du Ni par Mn et une addition massive en N permet \u00e0 cet acier de pr\u00e9server sa structure aust\u00e9nitique. La refusion PESR (Pressure ESR) lui assure tant sa propret\u00e9 microstructurale qu\u2019une microstructure uniforme et reproductible. Il en r\u00e9sulte un acier tr\u00e8s tenace poss\u00e9dant des propri\u00e9t\u00e9s m\u00e9caniques et de r\u00e9sistance \u00e0 la fatigue sup\u00e9rieures \u00e0 celles d\u2019un acier 316L satisfaisant les exigences de la norme ASTM F138. Cet acier ne contient pas de ferrite \u2202 (Delta). Il est nonmagn\u00e9tique. De par sa m\u00e9tallurgie et sa basse teneur en S, il r\u00e9siste bien \u00e0 la corrosion par piq\u00fbres et en crevasses notamment.<\/p>\n

Les particularit\u00e9s suivantes font de cet acier un mat\u00e9riau parfaitement adapt\u00e9 \u00e0 une utilisation m\u00e9dicale (chirurgie) :<\/p>\n<\/div>
