Der Cobalt-(Co)-Anteil in Hartmetallen diffundiert während des Diamantbeschichtungsprozesses in die Diamantschicht und mindert deren Haftfähigkeit. Siliciumcarbid-(SiC)-Zwischenschichten können als Diffusionsbarriere für Cobalt dienen und die konventionelle Ätzvorbehandlung der Substrate ersetzen. Im Rahmen einer Forschungsarbeit werden Beschichtungsprozesse mit SiC-Zwischenschicht entwickelt, diese Schichtsysteme auf verschiedene Substrate aufgebracht und durch Zerspanungsuntersuchungen bewertet.   The cobalt (Co) content in cemented carbide tools diffuses into the diamond layer during the coating process and reduces its adhesive strength. Siliciumcarbid-(SiC)-interlayers can serve as a diffusion barrier for cobalt and replace the conventional etching pre-treatment of blanks. In a research project different coating processes with SiC-interlayer are developed, the coating systems are applied to different substrates and evaluated in cutting experiments.

Aufgrund steigender Preise von Wolfram und Kobalt sind die Herstellkosten von Vollhartmetallwerkzeugen durch einen hohen Materialkostenanteil geprägt. Im Forschungsprojekt „Re-Tool 2“ erforscht das Institut für Fertigungstechnik und Werkzeugmaschinen (IFW) zusammen mit der Wulf Schleiftechnik GmbH einen Herstellungsprozess, um verschlissene Werkzeuge als Rohlinge für die Werkzeugherstellung zu verwenden. Durch einen Vergleich der Herstellung von umgeschliffenen und neugeschliffenen VHM-Werkzeugen soll das ökonomische und ökologische Einsparpotenzial der Methode gezeigt werden.   Due to the rising prices of tungsten and cobalt, the manufacturing costs of solid carbide tools are characterized by a high material cost share. In the research project „Re-Tool 2“, the IFW is researching in cooperation with Wulf Schleiftechnik GmbH a manufacturing process to use worn tools as blanks for tool production. By means of a comparison between the manufacturing and re-manufacturing process of tungsten carbide tools, the high economic and ecological savings potential is shown.
