Abstract
Description
Die Erfindung betrifft eine Kante oder Kufe für Wintersportgeräte nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to an edge or runner for winter sports equipment according to the preamble of claim 1.
Ein
Ski mit Kanten aus Keramikwerkstoff von teilstabilisiertem Zirkoniumoxid
ist z. B. aus der
Eine
keramische Gleitkufe für Eis, die unter anderem aus Zirkonoxid
bestehen kann, ist z. B. aus dem deutschen Gebrauchsmuster
Nachdem die dort beschriebenen Materialien bei der Herstellung von Wintersportgeräten aus nicht näher bekannten Gründen nicht zum Einsatz gekommen sind, liegt der Erfindung die Aufgabe zugrunde ein Material vorzuschlagen, das technisch und preislich zur Verwendung bei Wintersportgeräten geeignet ist.After this the materials described there in the production of winter sports equipment not used for reasons not known have come, the invention is the object of a material to propose that technically and priced for use in winter sports equipment suitable is.
Zur Lösung dieser Aufgabe soll das im kennzeichnenden Teil des Anspruchs 1 beschriebene Material verwendet werden.to This problem is solved in the characterizing part of claim 1 described.
Vorteilhafte Weiterbildungen der Erfindung sind in den untergeordneten Ansprüchen angegeben.advantageous Further developments of the invention are in the subordinate claims specified.
Die Vorteile des im Anspruch 1 beschriebenen Materials, dessen Verwendung in der Zahntechnik und Hüftgelenksprothetik bereits bekannt ist, liegt bei der Verwendung für Kanten oder Kufen für Wintersportgeräte in der hohen Härte, der hohen Bruchfestigkeit, einer hohen Biegefestigkeit und es unterliegt praktisch keiner Korrosion. Das Material ist im Gegensatz zu Aluminiumoxid-Keramiken deutlich weniger spröde und weist eine hohe Bruchzähigkeit auf, ist also auch für dynamische Belastungen einsetzbar. Ein weiterer Vorteil beim Einsatz im Wintersport ist die geringe Wärmeleitfähigkeit, die zur früheren Bildung eines das Gleitverhalten verbessernden Wasserfilms führt.The Advantages of the material described in claim 1, its use already known in dental technology and hip prosthetics is when using for edges or runners for Winter sports equipment in high hardness, high Breaking strength, high bending strength and it is practically no corrosion. The material is in contrast to alumina ceramics significantly less brittle and has a high fracture toughness, So it can also be used for dynamic loads. One Another advantage when used in winter sports is the low thermal conductivity, that for the earlier formation of a sliding behavior improving water film leads.
Insbesondere ist die gegenüber Stahl wesentlich verlängerte Standzeit eines derartigen Materials hervorzuheben.Especially is much longer than steel Stand life of such a material to emphasize.
