Abstract: A component comprises a silicon carbide substrate (10), a layer (14) of CVD diamond on a surface (12) of the substrate, and a smooth surface (14a) on the CVD diamond layer (14) which is a non-planar bearing or wear-resistant surface for the component.
Abstract: A surface of a diamond, particularly a diamond window, is treated by depositing a layer of a carbide-forming metal such as titanium, on the surface and thereafter removing the layer. The treatment has the effect of passivating stress surface defects in the diamond such as grain boundaries, twin defects and polishing damage.
