The invention relates to a process for producing a hard-material-coated component, comprising the following steps: application of a layer of hard material to the component in a PVD coating unit; and structural further processing of the outer surface of the layer of hard material, and to a component produced using the process. Particularly in the case of thick coatings or coatings with a columnar structure, such processes have a problem producing a sufficiently smooth surface on the coating. The problem is solved by the fact that for the structural further processing, the surface of the layer is blasted in a blasting device in order to improve this surface, an inorganic blasting agent with a grain size in the range from 1 &#x3bc;m to 100 &#x3bc;m and a sharp-edged grain shape being used.
