Description
Die ausführlichere Erläuterung der Erfindung erfolgt unter Bezugnahme auf die Zeichnungen. Darin zeigt
F i g. 9 die Form eines Werkstücks;
Fig.4 zeigt die Resultate der Messung der Gitterkonstanten von TiN von Sinterkörpern mittels eines Röntgenstrahlen-Diffraktometers, wobei die Sinterkörper bei einem Druck von 55 Kb und verschiedenen Drükken aus einem Gemisch von 60 Vol.-% pulverförmigen CBN hergestellt wurden, mit drei verschiedenen Teilchengrößen und 40 Vol.-% TiNo.72 (17,4% Stickstoffanteil in TiN), mit einer mittleren Teilchengröße von einem μπι. In der Figur zeigen die nicht ausgefüllten Vierecke einen CBN-Sinterkörper mit einer mittleren Teilchengröße von einem μπι, die Dreiecke beziehen sich auf drei μπι und die Kreise auf fünf μπι. Die Linie A gibt die Gitterkonstante des Sinterkörpers aus TiNo.72 an und die Linie B die Gitterkonstante des pulverförmigen Materials aus TiN<>,72.
Wurtzit-Bornitrid besteht aus hexagonalem Bornitrid durch ein Verfahren mit dynamischem Überdruck, das mit Schockwellen arbeitet. Das Material kann nach diesem Verfahren mit geringeren Kosten als CBN hergestellt werden, das zur Herstellung eine Einrichtung mit statischem Überdruck benötigt. Bei der Synthetisiermethode durch Schockwellen wirken hoher Druck und Temperatur nur während kurzer Zeitabschnitte. Dadurch kann ein Kristall nur kurzzeitig wachsen, so daß die erzielbare Teilchengröße von WBN gewöhnlich kleiner als 10 μπι ist. Außerdem ist das Teilchen kompliziert geformt und weist Vorsprünge und Vertiefungen in seiner Oberfläche auf, so daß es eine größere Oberfläche besitzt. Es bleiben deshalb auch bei dem oben beschriebenen Entgasungsverfahren Gasanteile zurück, die die Eigenschaften des Sinterkörpers verschlechtern. Zur Erzielung eines dicht konzentrierten Sinterkörpers arbeitet man deshalb besser mit einem Bindematerial, bei dem der erwähnte Wert kleiner ist als 0,97, vorzugsweise kleiner als 0,8. Aus den erwähnten Gründen ist in dem WBN-Pulver eine größere Menge Oxide adsorbiert als in dem CBN-Pulver. Dadurch saugt die Matrix bei Verwendung dieser Bindematerialien im Sinterkörper Sauerstoff auf, der durch die Auflösung der Oxide im WBN-Pulver entsteht, und der in die freien Atomstellen oder Atomlücken von C oder N des Bindematerials tritt, so daß eine feste Lösungsmasse aus M—C-O, M — N-O und/oder M—C—N-O entsteht. Bei Verwendung von TiN,als Bindemittel entsteht im Sinterkörper Ti(NO).
Da außerdem das für den Sinterkörper verwendete WBN aus hexagonalem Bornitrid durch Schockwellen entsteht, kann im WBN-Pulver auch hexagonales Bornitrid als Verunreinigung enthalten sein. Außerdem kann sich beim Sintern unter hohem Druck und hoher Temperatur das WBN in hexagonales Bornitrid zurückverwandein, da die WBN-Teilchen, bevor das Bindermaterial in die Zwischenräume zwischen den WBN-Teilchen eingedrungen ist, dem Druck nicht isostatisch ausgesetzt sind. Man kann hierzu Ai, Si und andere Metaiie als Katalysatoren zusetzen, die eine Rückumwandiung von WBN verhindern und eine Umwandlung des noch verbleibenden hexagonalen Bornitrids bewirken.
Der so gewonnene Sinterkörper wird mit einer Diamartscheibe flach geschliffen und dann mit Diamantpaste poliert Eine mikrofotografische Aufnahme der polierten Oberfläche zeigt F i g. 3, in der die schwarz erscheinenden Teilchen CBN-Kristalle sind, während der Platz um die Kristalle durch TiN ausgefüllt ist Die Röntgenstrahlen-Diffraktion zeigt neben CBN und TiN eine kleine Menge T1B2. Die Härtemessung mit einem Mikro-Duro-
