04442180 is referenced by 10 patents and cites 11 patents.

The invention relates to a sintered body for use in a cutting tool comprising a cutting edge forming part having particularly high hardness and wear resistance bonded to a supporting member having high plastic deformability, stiffness, transverse rupture strength, thermal conductivity, thermal expansion coefficient, resistance to corrosion, oxidization and the like, and to a method for producing the same. A diamond powder or high pressure form boron nitride powder is placed in contact with preliminarily sintered cermet constituted by carbide crystals chiefly comprising molibdenum in the form of (Mo, W)C bonded by iron group metals, the combined body being sintered at a temperature and pressure under which the diamond powder or high pressure form boron nitride powder is thermodynamically stable so that the sintered body of the diamond or high pressure form boron nitride is bonded to the cermet thereby enabling to obtain a sintered body having the said high properties for use in a cutting tool.
