METHOD FOR COATING A SUBSTRATE AND METAL ALLOY VACUUM DEPOSITION FACILITY

摘要

The invention relates to a method for coating a substrate (S) by continuously depositing on said substrate (S) a layer of a metal alloy including at least two metallic elements using a vacuum deposition facility (1) that comprises a vapour jet coating device (7) for spraying the substrate (S) with a vapour containing the metallic elements in a predetermined and constant relative proportion, wherein the vapour is previously accelerated to a sonic speed. The method is particularly intended for depositing Zn-Mg coatings. The invention also relates to a continuous metal alloy vacuum deposition facility (1) for implementing said method.
