1. A method for the fabrication of a coated sheet comprising the steps of:
providing a sheet in a deposition chamber;
maintaining the deposition chamber at a pressure Pchamber,
maintaining an ejection chamber that is located inside the deposition chamber at a pressure Peject, a ratio of the pressure Pchamber to Peject being between 2·10−3 and 5.5·10−2;
coating the sheet with coating with a sonic vapor jet, wherein the coating consists essentially of zinc, and wherein the sonic vapor jet coats the sheet via jet vapor deposition; and
wherein the pressure inside the ejection chamber is about 3.4 mbar.
