ABSTRACT:
A method of producing a composite abrasive compact is provided. The method includes the steps of providing a cemented carbide substrate having two layers separated by a metallic layer. The metal of the metallic layer may be a ductile metal such as cobalt or nickel or a refractory, carbide-forming metal such as molybdenum, tantalum, niobium, hafnium, titanium or zirconium. A layer of the components, in particulate form, necessary to produce an abrasive compact is placed in a recess of the one layer to produce an unbonded assembly. The unbonded assembly is then subjected to suitable conditions of elevated temperature and pressure to produce an abrasive compact from the components.
