摘要 |
A method is provided for producing a tool component which comprises a CVD diamond layer (16) bonded to a cemented carbide substrate (20). The method includes the steps of providing a mass of carbide particles bonded into a layer (10) with an organic binder, removing the organic binder to produce a porous mass of the particles, depositing a layer (16) of diamond by CVD on a surface (12) of the porous mass, placing the porous mass in contact with a layer (18) 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 (20) for the CVD diamond layer (16). <IMAGE> |
