Pièces artificielles de prothèse pour l'intérieur du corps de l'homme ou des animaux, en particulier des pièces de prothèse pour la mastication.
La présente invention se rapporte à des pièces artificielles de prothèse pour l'intérieur du corps de l'homme ou des animaux, en particulier à des pièces de prothèse pour la mastication (y compris leurs organes de fixation) et elle consiste en ce que ces pièces sont fabriquées par coulée en moule d'alliages chrômecobalt résistant à la corrosion, qui contiennent 0.01
<Desc/Clms Page number 2>
à 1 % de carbone, 6 à 30 % de chrome, 40 à 90 % de cobalt, et le reste de fer ou nickel ou de ces deux métaux à la fois.
En outre, on peut ajouter à ces alliages encore d'autres éléments d'addition employés couramment dans la technique des alliages, par exemple du silicium, manganèse, tungstène, molybdène, aluminium, titane, vanadium, glucinium, bore, ec, séparément ou ensemble, en proportions pouvant aller jusqu'à 6 %.
Il a été constaté que les pièces fabriquées en ces alliages résistant à des influences oxydantes, à l'attaque de sucs du corps, par exemple de salive, et de médicaments, comme d'ailleurs à des agents chimiques (acide lactique, acide acétique, acides gras, hydrogène sulfuré) et n'exercent pas d'action sur les nerfs du goût, au moins dans la même mesure que des pièces, à la fabrication desquelles on emploie des alliages austénitiques fer-chrôme-nickel.
Par rapport à ces pièces coulées en moule, employées jusqu'ici comme pièces de prothèse pour le corps de l'homme ou des animaux, les pièces fabriquées conformément à l'invention se distinguent en ce que les alliages mentionnés remplissent de la meilleure manière possible les moules, même pour de faibles épaisseurs de paroi, de telle manière que les plus petites pièces de moulage peuvent également être coulées de façon précise sans difficulté, et que les pièces de moulage achevées présentent en outre une grande élasticité, propriété que ne possèdent pas les pièces de moulage en alliages austénitiques fer-chrôme-nickel employées
<Desc/Clms Page number 3>
jusqu'ici dans ce but. En outre, les alliages de laissent bien braser et polir et résistent bien à un rayage par suite de leur dureté.
Il a été constaté qu'on obtient des résultats partioulièrement avantageux avec un alliage présentant sensiblement la composition suivante : 0.25 % de carbone, 25 % de chrome, 65 % de cobalt, 1 % de fer, 1% de nickel, 1 % de manganèse, 5 % de tungstène.
Les propriétés des alliages suivant l'invention peuvent également être améliorées par un traitement thermique . C'est ainsi, par exemple, que la dureté de l'alliage mentionné ci-dessus peut être notablement accrue par un traitement thermique.

Artificial parts of prosthesis for the interior of the body of man or animals, in particular parts of prosthesis for chewing.
The present invention relates to artificial parts of prosthesis for the interior of the body of man or animals, in particular to parts of prosthesis for chewing (including their fixing members) and it consists in that these parts are made by mold casting of corrosion resistant chrômecobalt alloys, which contain 0.01
<Desc / Clms Page number 2>
at 1% carbon, 6-30% chromium, 40-90% cobalt, and the remainder of iron or nickel or both of these metals at the same time.
In addition, it is possible to add to these alloys still other addition elements commonly employed in the alloying art, for example silicon, manganese, tungsten, molybdenum, aluminum, titanium, vanadium, glucinium, boron, ec, separately or. together, in proportions of up to 6%.
It was found that the parts made of these alloys resistant to oxidative influences, to attack by body juices, for example saliva, and drugs, as moreover to chemical agents (lactic acid, acetic acid, fatty acids, hydrogen sulphide) and do not exert an action on the nerves of taste, at least to the same extent as parts, in the manufacture of which austenitic iron-chrome-nickel alloys are used.
Compared to these mold-cast parts, hitherto used as prosthetic parts for the body of humans or animals, the parts produced in accordance with the invention differ in that the alloys mentioned fulfill in the best possible way. molds, even for small wall thicknesses, in such a way that the smallest molding parts can also be precisely cast without difficulty, and the finished molding parts additionally exhibit high elasticity, a property which does not have the casting parts in austenitic iron-chromium-nickel alloys used
<Desc / Clms Page number 3>
so far for this purpose. In addition, the alloys solder and polish well and resist scratching well due to their hardness.
It has been found that particularly advantageous results are obtained with an alloy having substantially the following composition: 0.25% carbon, 25% chromium, 65% cobalt, 1% iron, 1% nickel, 1% manganese , 5% tungsten.
The properties of the alloys according to the invention can also be improved by heat treatment. Thus, for example, the hardness of the above-mentioned alloy can be significantly increased by heat treatment.
