摘要
A process for the continuous production of coated metallic bands obtained by physical phase vapor deposition includes the following steps carried out on a band, eventually coated with zinc or its alloys, in motion and maintained in a vacuum environment:;heating the band to be coated;;activating the band surface;;heat stabilizing the band;;depositing a zinc layer on the metallic band;;secondary heat stabilizing the band; and;depositing one or more elements or compounds on the zinc layer, these elements being able to synergistically interact with the zinc layer to obtain high corrosion resistance, weldability, ductility, and adhesion.
