Abstract
The formation of uniformly high quality abrasive compacts, especially cubic boron nitride compacts, is achieved by employing a substrate material (comprising a carbide such as tungsten carbide and a ferrous metal such as cobalt) having a titanium content of not greater than 100 ppm as shown by analysis. Preferably, the maximum tantalum content is also not greater than 100 ppm.
Claims11
A method for producing an abrasive compact which comprises:
- (1) forming a substrate material comprising a carbide support material and a binder metal wherein said substrate material has a titanium content no greater than 100 ppm;
- and
- (2) subjecting a combination of said substrate material, a catalyst/solvent material and abrasive particles to high pressure, high temperature conditions effective to sweep said catalyst/solvent material through said abrasive particles to bond and sinter said abrasive particles.
