A method for the selective surface treatment of a first workpiece on at least one of the metalized areas of the upper and/or underside, the first workpiece being releasably jointed to at least one additional workpiece on one of its faces so as to be sealed from the exterior in at least one partial area and the selective surface treatment of the areas not covered by the joined section being carried out in a treatment phase. Cooling and distribution of the metalized areas is made easier because the first workpiece is not flat and has on at east one face identically or different metalized areas or cavities across a whole or part of a surface. It also has at least one additional metallic protective layer or an additional metallic coating applied during the selective surface treatment. |
