摘要： The present invention relates to ceramic cutting tools, such as, a aluminum oxide with zirconium oxide ceramic cutting tool with diffusion bonding enhanced layer and CVD coatings, particularly useful for machining modem metal materials. The method comprises a chemical reaction with a mixture including nitrogen and aluminum chloride introduced to form a diffusion bonding enhanced layer between the ceramic substrate and the CVD coatings. Thus formed diffusion bonding is highly adherent to the aluminum oxide with zirconium oxide ceramic substrate and significantly enhances the CVD coating properties, and thus improving the machining performance in terms of the tool life of zirconium-based aluminum oxide with zirconium oxide ceramic cutting tools.

摘要： The present invention relates to the PVD coated tungsten carbide (WC) based cemented cutting inserts with ruthenium (Ru) as a key chemical element, or a key feature, in the cobalt (Co)-based binder phase, particularly useful for machining today's mold & die materials. In the Ru—Co mixed binder phase in the tungsten carbide substrate, the ratio of Ru/Co is at least 3%, by weight. The Ru-featured carbide cutting insert provided in this invention is PVD coated with one or more layers by a modern PVD coating technology. The development of the PVD coated Ru-featured carbide cutting inserts provided in this invention is based on a discovery that the unique combination of PVD coating techniques and Ru-featured carbide cutting inserts demonstrates superior machining performance in today's mold & die machining applications.
