Plasma aided coating of workpieces made of light metals or light-metal alloys includes production of an intermediate metal oxide layer on the workpiece surface by anodic oxidation, and drying of this layer prior to plasma aided coating

摘要

A workpiece (10) is provided with an intermediate metal oxide layer (20) by anodic oxidation. This layer is dried, and a desired coating (30) is subsequently formed by means of a plasma aided coating process.
