Abstract:
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 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 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.

Abstract:
A plate made of inorganic material comprises a support layer (1') of low thermal conductivity. Said layer is comprised of exfoliated vermiculite and a binder of compressed bodies treated at a temperature higher than 800 C and preferably 900 C, having preferably a density between 700 C and 1,400 kg/m . The plate may be coated on one side with a ceramic layer (4) such as ceramic enamel. In an alternative for paving, the support layer (1') may be provided with a protection layer (3') of terracotta. To produce such plate, a support plate (1) is formed preferably by thickening and hardening the binder-vermiculite mixture, and the support plate is then treated at a temperature higher than 800 C. Simultaneously or subsequently, one of the front faces is optionally provided with a ceramic layer. The plate may be used for wall and ceiling cladding with the aim of reducing the acoustical reflection.

Abstract:
A cubic boron nitride sintered material where wear resistance is suppressed from decreasing having excellent chipping resistance and a cutting tool made thereof are provided. The sintered material is constituted from cubic boron nitride particles that are bound by a binder phase, while the binder phase contains a carbide of at least one kind of metal element selected from among metals of groups 4, 5 and 6 of the periodic table and a nitride of at least one kind of metal element selected from among metals of groups 4, 5 and 6 of the periodic table coexisting therein, and therefore the particles can be suppressed from coming off and the binder phase can be suppressed from wearing and coming off at the same time, thereby making the sintered material having high wear resistance and particularly excellent chipping resistance.
