摘要

Process for coating a surface of a substrate (2) with a coating material comprises pre-treating the surface using a laser (3), and coating the surface with the coating material. An Independent claim is also included for a vacuum deposition arrangement comprising a laser for pre-treating the substrate surface. Preferred Features: The laser is integrated into the vacuum deposition arrangement. The substrate is made from metal, glass, ceramic or plastic. An exchangeable window (5) is arranged between the laser and the surface of the substrate. The coating material is applied in a PVD, CVD or sol-gel process.
