BONDING METHOD BETWEEN CEMENTED CARBIDE MEMBER AND DIAMOND MEMBER, BONDING STRUCTURE, CUTTING BLADE CHIP FOR DRILLING TOOL, CUTTING BLADE MEMBER, AND DRILLING TOOL

摘要

PROBLEM TO BE SOLVED: To provide a bonding method for increasing bonding strength more than ever between a member made of cemented carbide and a member made of diamond, a bonding structure, a cutting blade chip for drilling tool, a cutting blade member, and a drilling tool. SOLUTION: The cutting blade chip used for the cutting blade of the drilling tool has a structure comprising a cutting blade body part 11 made of the cemented carbide (the cemented carbide member), the member 12 made of diamond supported by the cutting blade body part 11, and a metal layer 13 that is arranged between the cutting blade body part 11 and the diamond member 12 and diffusion-bonded with them respectively. The metal layer 13 is composed of either one kind of the organic metal among the complexes [Ti(O-i-Bu)2(Me-dhd)2] and Zr(Me-dhd)4. COPYRIGHT: (C)2005,JPO&NCIPI
