A set-up for thermochemical polishing of CVD diamond films has been developed. The removal rate of the polishing and the roughness versus temperature, plate velocity and pressure has been measured. The general conclusion is: the higher the temperature the higher the removal rate and roughness. The highest removal rate obtained on flat samples at 1020∘C is less than 10 nm. The sharpness of edges between two polished surfaces is about 20 nm. The perspectives of the thermochemical method for the polishing of diamond will be discussed.
