Zusammenfassung
(DE)
Keramische Werkstoffe sind spröde und deshalb in der Regel nicht für dynamische Belastungen, insbesondere durch Vibrationen und Stöße hervorgerufen, geeignet. Erfindungsgemäß wird deshalb ein Werkstoff vorgeschlagen, zusammengesetzt aus einem hohen Anteil an Aluminiumoxid sowie Zirkonoxid und Strontiumaluminat.
(EN)
Ceramic materials are brittle and are therefore not generally suitable for dynamic stresses, in particular caused by vibration and impact. The invention therefore discloses a material composed of a large fraction of aluminium oxide, zirconium oxide and strontium aluminate.
(FR)
Les matériaux céramiques sont fragiles et ne sont donc pas appropriés, en règle générale, pour être soumis à des contraintes dynamiques, notamment engendrées par des vibrations et des chocs. L'invention concerne donc un matériau composé d'une forte proportion d'oxyde d'aluminium ainsi que d'oxyde de zirconium et d'aluminate de strontium.
