摘要：
本发明涉及一种用于涂覆金属带材的方法，该方法包括：在真空中将可氧化金属或可氧化金属合金的层沉积在预先涂覆有锌或锌合金的金属带材上，将涂覆的金属带材盘绕，且对卷绕的带材施加静态扩散处理以便获得具有涂层的带材，该涂层在上方部分包含由可氧化金属或可氧化金属合金在锌或锌合金层的全部或部分中扩散所形成的合金层。本发明还涉及用于实施所述方法的设备。
摘要（英）：

The invention relates to a method for coating a metal strip that comprises depositing in a vacuum a layer of an oxidizable metal or oxidizable metal alloy or metal oxide on a metal strip previously coated with zinc or a zinc alloy, winding the coated metal strip, and applying a static diffusion processing to the wound strip in order to obtain a strip with a coating that includes, at the upper portion, a layer of an alloy formed by the diffusion of the oxidizable metal or oxidizable metal alloy in the entirety or in a portion of the zinc or zinc-alloy layer. The invention also relates to equipment for implementing said method.
