METHOD FOR JOINING A DIAMOND LAYER TO A SUBSTRATE, AND DIAMOND-COATED SUBSTRATE

摘要

The invention relates to a method for producing a substrate (1) coated with a diamond layer (2). According to the inventive method, a substrate (1) is prepared, said substrate having a layer (3) which extends from the surface (O) of the substrate towards the inside, comprises recesses (4) extending from the surface (O) towards the inside, and is elastically and/or plastically deformable in an xy-plane which is parallel to the surface (O), and a diamond layer (2) engaging in the recesses is then produced by means of a CVD method. Cooling stresses occurring in the diamond layer (2) during cooling are essentially compensated by an elastic and/or plastic deformation of the layer (3) in the xy-plane.
