Verfahren zur Herstellung eines diamantbeschichteten Metallkörpers

The method for producing a polycrystalline diamond coating (24) on a metal component consists of: (a) producing a metal substrate (26) with the surface to be coated containing titanium; (b) applying a carbon fastening layer (28) contg. at least 10 per cent graphitic or amorphous carbon, and is later...

Zusammenfassung:	The method for producing a polycrystalline diamond coating (24) on a metal component consists of: (a) producing a metal substrate (26) with the surface to be coated containing titanium; (b) applying a carbon fastening layer (28) contg. at least 10 per cent graphitic or amorphous carbon, and is later diffused entirely into the surface to be coated with diamond; and (c) depositing a diamond coating on the carbon fastening layer. Also claimed is a resultant metal component coated by the proposed method. The component is characterised by the presence of an intermediate carbon layer (28), and by the fact that the diamond coating has a thickness of 1 - 10 microns.
