    Abstract: A method for diffusing titanium and nitride into a base material having a generally compact, granular microstructure (e.g., carbide). The method generally includes the steps of providing a base material having a generally compact, granular microstructure; providing a salt bath which includes sodium dioxide and a salt selected from the group consisting of sodium cyanate and potassium cyanate; dispersing metallic titanium formed by electrolysis of a titanium compound in the bath; heating the salt bath to a temperature ranging from about 430° C. to about 670° C.; and soaking the base material in the salt bath for a time of from about 10 minutes to about 24 hours. In accordance with another aspect of the present invention, the base material may further be treated with conventional surface treatments or coatings.

    Abstract: There is provided a wear-resistant chain having a high durability even in severe use environments such as those of a timing chain of an engine even though it is highly efficient and productive. A miniaturizing agent containing silicon is doped in a vanadium cementation process of a base material of steel. Vanadium carbide forming a surface-hardened layer contains a secondary phase composed of an amorphous structure containing silicon within crystal grains and a crystal grain size of the vanadium carbide is miniaturized to 1 μm or less.

    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 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.

    Abstract: A mixed powder layer is applied by coating to a cavity of a forging die made of an Fe-base alloy, at least to the region of the cavity to be reinforced or repaired, the mixed powder layer comprising the first element powder capable of being converted into a carbide to enhance the hardness of the forging die and the second element powder having a melting point lower than that of the first element powder. Die reinforcing is carried out by forging a work by using a forging die covered with the mixed powder layer and heat-treating the die by utilizing the working heat generated in the forging to thereby make the layer reflow and diffuse the carbide in the die.
