ABSTRACT:
Process for the formation of a removable surface area of a specific depth on a substrate with all coatings seated on the surface of the substrate, wherein a layer of a material, thin as related to the substrate, with a thermal expansion coefficient strongly deviating as compared with the substrate, is bonded to the substrate at one temperature and is subsequently cooled to another temperature.
