Abstract

PURPOSE:To provide a composite sintered diamond with very strong part of conjunction free from stressed deflection and crack, by interposing zirconium between powder lumps containing diamonds and super-hard alloy which shall be firmly sintered and combined under super-high pressure and temperature. CONSTITUTION:At least one kind of powder of ferrous metals such as iron, cobalt, etc. is added to diamond powder and sufficiently stirred and mixed by a pole mill beforehand. Then, super-hard alloy consisting of at least one kind of carbide, nitride and nitric carbide of groups 4a, 5a and 6a on the periodic table and at least one kind of Fe, Co, Ni, Mo and Cr is placed in a reactor. Next, a zirconium plate with a desired thickness is placed on it. Furthermore, on the zirconium plate is placed said diamond powder mixture. The reactor thus set is subjected to super- high pressure and temperature to sinter said powder so that the sintered diamond and super-hard alloy can be firmly combined to provide composite sintered diamond for tools.
