Diamond coated tool, especially a machining tool or dental tool, has adjustable surface topography obtained by sintering particles to tool body prior to diamond layer deposition

摘要

Diamond coated tool with an adjustable surface topography is obtained by sintering particles (7) to the tool body (3) prior to diamond layer (6) deposition. An Independent claim is also included for production of the above diamond coated tool. Preferred Features: The tool body (3) is a sintered or green hard metal or ceramic body, and the particles (7) consist of the same material as the hard material phase of the tool material. The diamond layer (6) is deposited by hot filament CVD.
