Title:
SINTERED METAL-BASE DIAMOND COMPOSITE MATERIAL AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH0987791
Kind Code:
A
Abstract:

To produce a diamond composite material having high rigidity without considerably deteriorating ductility peculiar to a metal to be the matrix.

Diamond particles 12 are dispersed in a matrix 11 obtd. by sintering a carbide forming metal or an alloy contg. a carbide forming metal to produce the objective sintered metal-base diamond composite material. This composite material has a carbide layer 13 at the interface between the matrix 11 and each of the diamond particles 12 and tight bonding is attained by the layer 13. The diamond particles 12 have 0.01-100μm particle diameter and are contained in the matrix preferably by 1-50vol.%.
