Abstract: Equipment for manufacturing a metal strip coated by a process that includes vacuum-depositing a layer of an oxidizable metal or an oxidizable metal alloy on a metal strip precoated with zinc or with a zinc alloy, then coiling the coated metal strip, then oxidizing a surface of the metal strip coated with the oxidizable metal or oxidizable metal alloy and treating the oxidized wound coil with a static diffusion treatment to obtain a strip having a coating that includes, in an upper portion, a layer of an alloy formed by diffusion of the oxidizable metal or the oxidizable metal alloy in all or part of the zinc or zinc alloy layer. The equipment includes a device for galvanizing the metal strip, a vacuum deposition coating device, and a static heat treatment device operating in a controlled atmosphere.

Abstract: A vacuum deposition facility for continuously depositing coatings formed from metal alloys having at least two metallic elements on a running substrate is provided. The vacuum deposition facility includes a vacuum deposition chamber, a substrate running through the vacuum deposition chamber and an evaporation crucible inside the vacuum deposition chamber. The evaporation crucible includes a heater and a bath of molten metal alloy which has at least two metallic elements in a predetermined and constant ratio. The evaporation crucible evaporates the molten metal alloy into a vapor. The vacuum deposition facility also includes a coater inside the vacuum deposition chamber and connected to the evaporation crucible. The coater sprays a face of the running substrate with the vapor at a sonic velocity in order to deposit a coating on the running substrate. The vapor includes the at least two metallic elements in the predetermined and constant ratio.
