Abstract
In a process for coating a substrate, a texture (,) is created in a portion of its surface. A first layer (,) to be applied on the surface of the substrate adheres better to the texture (,) than it does to a surface area located outside of the texture (,). Then, the layer (,) is applied to the surface of the substrate and after that, areas of the layer projecting laterally beyond the texture (,) are mechanically removed. The material of the texture (,) contains at least one chemical element or a compound, which the layer (,) does not have or has only in a smaller concentration than the material of the texture (,). On the first layer (,), at least one second layer (,) is then applied which does not have the chemical element or compound contained in the material of the texture (,), or it has it only in a smaller concentration than the material of the texture (,). The process makes it possible to apply to a substrate a textured layer, which has surface properties that remain for the most part unchanged when it is heated.
