Title: This disclosure relates to a method of fabricating composite blocks
Inventor: LIN SHUEN-TIAN
IPC: B22F7/00
Filed: 1999-06-16
Granted: 2000-09-01
Abstract: This disclosure relates to a method of fabricating composite blocks that are composed of diamond grits and iron based metal matrix, and are intended to be used as cutting and grinding tools. In this disclosure, mixed metallic powders which is mainly composed of carbonyl iron powder are initially blended with titanium coated diamond grits and an organic binder. The blend is then processed into granules of controlled sizes. The granules are subsequently uni-axially pressed into green components, which in turn are pressureless-sintered in a controlled atmosphere such as hydrogen atmosphere and vacuum. Such a process route is more cost-effective than conventional hot-pressing method, and the bonding strength between diamond grits and metal matrix is also significantly improved. In addition, the hardness of the metal matrix can be adjusted by varying the composition of the metal matrix.
