Abstract

Diamond tools are widely used in cutting process of natural stones. In the manufacturing process of diamond tools, matrix material can be sintered via different sintering methods such as spark plasma sintering (SPS), hot isostatic pressing (HIP) and conventional sintering (CS). CS method provides higher production capacity and lower cost when compared to other sintering methods, but mechanical properties are inferior to other sintering methods. Recent studies have the aim to obtain similar performance level as achieved by means of CS method. In this study, samples were prepared with three different compositions to be used for the CS method and characterized to evaluate their performance as a diamond bead matrix material. Experimental results showed that a study can be conducted to reach similar performances with Co matrix by using Ni matrix, and a high copper rate in matrix is undesirable since diamond tools are exposed to impact forces.

Kurzfassung

Diamantwerkzeuge werden breitflächig für das Schneiden von Naturstein eingesetzt. Bei dem Herstellungsprozess von Diamantwerkzeugen kann das Matrixmaterial mit verschiedenen Verfahren gesintert werden, wie zum Beispiel das Spark Plasma Sintern (SPS), das Heiß-Isostatische Sintern (Hot Isostatic Pressing (HIP)) und das herkömmliche Sintern (Conventional Sintering (CS)). CS bietet höhere Produktionskapazitäten und niedrigere Kosten im Vergleich zu anderen Sinterverfahren, allerdings sind die Eigenschaften schlechter als bei anderen Sinterverfahren. In den letzten Jahren ist es das Ziel, ähnliche Eigenschaften der hergestellten Werkstoffe bei der Verwendung von CS zu erhalten. In der diesem Beitrag zugrunde liegenden Studie wurden Proben mit drei verschiedenen Zusammensetzungen mittels CS hergestellt und charakterisiert, um ihre Eigenschaften als Material für Diamantbeschichtungen zu bewerten. Die experimentellen Ergebnisse zeigten, dass ähnliche Eigenschaften mit einer Co-Matrix unter Verwendung einer Ni-Matrix erhalten werden können und ein hoher Kupferanteil in der Matrix nicht erwünscht ist, weil die Diamantwerkzeuge schlagartigen Beanspruchungen ausgesetzt sind.
