  • Patent number: 8293358
    Abstract: When a ceramic substrate is manufactured through a constraint firing step that uses a constraining layer, the constraining layer is removed without causing significant damage to a sintered base layer or an electrode formed on the surface of the sintered base layer, and the electrode can be reliably exposed. A green stacked body having a base layer and a constraining layer disposed so as to be in contact with at least one principal surface of the base layer is formed. A fired stacked body having a sintered base layer and a green constraining layer is then obtained by firing the green stacked body to sinter the base layer. Subsequently, the constraining layer is removed from the sintered base layer by vibrating media that are disposed so as to be in contact with the constraining layer.

  • Patent number: 8173248
    Abstract: A PVD coating is disclosed, and in particular a nanoscale multilayer superlattice PVD coating comprising high hardness, a low friction coefficient and increased chemical inertness. The multilayer coating comprises a repeating bilayer represented by (VxMe(i-x))CyN(i-y)/(MezV(1-z))CyN(i-y) where 0.1?x?0.9; 0.01<y<0.99 and 0.1?z?0.9 and Me is a substantially pure metal or a metal alloy. The composition of the coating through the layers alternates from layer to layer according to a V-rich layer and a Me-rich layer modulated sequence. Vanadium is incorporated within the layer composition and has been found to act as a lubricating agent during sliding wear. Carbon, also incorporated within the coating, serves to further stabilize the friction coefficient thereby increasing the chemical inertness between cutting tool and workpiece material.

  • Patent number: 8147992
    Abstract: The present invention relates to ceramic cutting tools, such as, an aluminum oxide with zirconium oxide ceramic cutting tool with diffusion bonding enhanced layer and CVD coatings, particularly useful for machining modern 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 enhanced layer is highly adherent to the aluminum oxide with zirconium oxide ceramic substrate and significantly enhances the CVD coating properties, thus improving the machining performance in terms of the tool life of zirconium-based aluminum oxide with zirconium oxide ceramic cutting tools.
