Abstract: A dicing blade is formed by plating a composition of diamond particles and silicon carbide whiskers suspended in a nickel solution upon an aluminum hub. To obtain bonding rather than capturing of the diamond particles, nickel coated diamond particles may be used to form an inter-metallic bond between the coated diamond particles, the silicon carbide whiskers and the nickel matrix.

Abstract: Super-hard grinding particles are electrodeposited on a metallic grinder matrix having recessed portions defined in an outer peripheral surface thereof to thereby produce a desired grinder used for a grinding machine. The grinder matrix is disposed within a mesh-like grinding-particle holder provided in a plating tank. Further, the grinding particles are packed into the grinding-particles holder. The grinding particles held in contact with the recessed portions of the grinder matrix are bonded to the grinder matrix using a plating layer formed by electroplating. The grinder matrix is reversed upsidedown and holding the grinding particles in contact with the recessed portions of the reversed grinder matrix. The grinding particles are bonded again to the grinder matrix using a plating layer formed by electroplating.

Abstract: Metal oxides are formed at low temperatures by the process of providing a class of divalent metal hydroxycarboxylates designed to react with metal alkoxide compounds such as B(OR').sub.4, where B=Ti, Zr, Sn and R'=an alkyl group with the elimination of two equivalents of alcohol to form species with integral or non-integral stoichiometry. The reaction produces an intermediate compound which after thermolysis at 350.degree. C. in O.sub.2, results in formation of crystalline perovskite phase materials of general formula ABO.sub.3, A.sub.x A'.sub.1-x BO.sub.3 and AB.sub.x B'.sub.1-x O.sub.3.

Abstract: A titanium nitride coating (or equivalent metal or alloy) is applied over the abrasive surface of conventional CBN and diamond tools by the process of physical vapor deposition at temperatures below the tempering temperature of the core metal and below the temperature at which the difference between the coefficients of expansion of the substrate and of the abrasive causes stresses that damage the bond between them. Specific operating conditions are required during the deposition process in order to ensure the proper level of adhesion of the titanium nitride layer to the underlying material. Under these conditions, the process does not affect the integrity of the steel core of the grinding tool and the titanium nitride or equivalent coating stabilizes and reinforces the existing bond between the cubic boron nitride or diamond and the core, resulting in a grinding tool with greater efficiency and longer life.
