Title:
DIAMOND-BASED CONDUCTIVE HARD SINTERED MATERIAL AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2020147462
Kind Code:
A
Abstract:
To provide a sintered material that can be applied to a processing tool for all materials including iron, suppresses promotion of phase transition to graphite caused by a bonding material, and can be manufactured and processed under the same conditions as a cobalt-based diamond sintered material.SOLUTION: A diamond-based conductive hard sintered material of the present invention comprises the sintered material that is made up of a first component group consisting of sized diamond particle and boron, and a second component group consisting of borides, carbides and composite compounds of single or multiple metallic components selected from Group IV, Group V, or Group VI elements of a periodic table, is a reaction product of each metallic material corresponding to the borides, carbides and composite compounds in the second component group with the diamond particles or boron in the first component group, in which the diamond particles are fixed and integrally bonded to each other via the boride, carbide, and composite compound, and exhibits conductivity based on the carbides, borides and composite compound phases.SELECTED DRAWING: None
