A steel sheet is provided with a coating having at least one layer of zinc and a top layer of paint applied by cataphoresis. The zinc layer is deposited by a jet vapor deposition process in a deposition chamber maintained at a pressure between 6&#xb7;10mbar and 2&#xb7;10mbar. A fabrication method and an installation are also provided.

A steel sheet is provided with a coating having at least one layer of zinc and a top layer of paint applied by cataphoresis. The zinc layer is deposited by a jet vapor deposition process in a deposition chamber maintained at a pressure between 6&#xb7;10mbar and 2&#xb7;10mbar. A fabrication method is also provided.

A steel sheet is provided. The steel sheet includes a multilayer coating including at least one zinc-based layer being 0.1% to 20% magnesium by weight which is covered by a fine temporary protective layer of 5 to 100 nm. The fine temporary protective layer is composed of metal or metal oxide selected from the group consisting of aluminum, chromium, aluminum oxides AlOx, with x being strictly between 0.01 and 1.5 and chromium oxides CrOy, with y being strictly between 0.01 and 1.5. The at least one zinc-based layer is not alloyed with the temporary protective layer. Manufacturing methods for a sheet and part are also provided.

Steel sheet including a multilayer coating and methods

A coating process for coating at least one side of a running substrate, by vacuum evaporation, with a layer of a sublimable metal or metal alloy, in which said metal or metal alloy is positioned so as to face said side of the substrate in the form of at least two ingots placed in contact with one another, that surface of said ingots facing said side of the substrate being kept parallel to the substrate and at a constant distance from the latter during coating, and also to a coating plant for implementing the process and to a feeder for supply.
