Abstract

The invention relates to a body with a substrate (1), an intermediate layer (2) applied on top thereof and a CVD diamond layer (3) applied to the intermediate layer. In order to propose a body coated with CVD diamond and a production process, in which the body has an increased load-bearing capacity under various mechanical loads, provision is made for the intermediate layer to be predominantly metallic, wherein the metal fraction of the intermediate layer consists predominantly of tungsten and/or chromium, and for the intermediate layer to have a roughness defined by an Rz value of 0.5 μm-3.0 μm.
