ABSTRACT:
A method is provided for producing a tool component which comprises a CVD diamond layer bonded to a cemented carbide substrate. The method includes the steps of providing a mass of carbide particles bonded into a layer with an organic binder, removing the organic binder to produce a porous mass of the particles, depositing a layer of diamond by CVD on a surface of the porous mass, placing the porous mass in contact with a layer of binder metal particles bonded with an organic binder, and heating the product to allow the metal binder particles to melt and infiltrate the carbide particles and produce a cemented carbide substrate for the CVD diamond layer.
