Abstract
Known process for the metallization of non-conductors, particularly synthetic resins, by chemical deposition, evaporation, or sputtering operate with adhesion facilitating intermediate layers such as e.g. varnishes or pastes. There is not attained sufficient adhesiveness with these adhesion facilitators for many areas of use. Besides the adhesive facilitator can cause troubles in later processing. Therefore there is described a process in which the surface area to be coated is roughened by means of a preliminary etching before by the metallizing and wherein this surface area before the etching is exposed to a heavy ion radiation.
Claims8
In a process for the production of an adhesive metal coating on a non-conductor chemically, by evaporation in a vacuum or by sputtering through roughening, the region of the surface to be coated by means of an etching process before the metallization, the improvement comprising exposing the region of the surface to be coated before the etching process to heavy ion radiation, the heavy ions having a mass of at least 10 and an energy of greater than 0.1 meV per nucleon.
