SUMMARY:JET VAPOUR DEPOSITION: A novel high-productivity vacuum coating technique with superior properties offering steelmakers worldwide a high degree of coating flexibility and a wide range of new possibilities.
DESCRIPTION:In 2016, the ArcelorMittal Group became the first steelmaker to industrialize the vacuum deposition technology to galvanize steel strip. Known under the name of "Jet Vapour Deposition (JVD)", this new type of zinc coating technology in which a zinc vapor is continuously deposited onto a steel strip in a vacuum chamber. Compared to Electro-Galvanizing (EG) and Hot-Dip Galvanizing (HDG), the JVD technology allows to apply with high productivity single-side, as well as double-sided coatings with zinc thicknesses that can differentiate from one side of the steel to the other.
Circumventing the major constraints of these conventional coating processes, the JVD technology allows for the optimal coating of Advanced High Strength Steels (AHSS). As such, the JVD technology prevents the hydrogen embrittlement identified as a major drawback of the EG process for the coating of AHSS. Additionally, the JVD technology also overcomes the negative influence of steel surface oxidation when using the HDG process for the coating of certain types of AHSS 
Today, after 6 years of production, the industrialization of the JVD steel coating line is a success. At the end of 2022, the JVD line produced over 800,000 tons of galvanized steel strip.
To address all industrial constraints and make the JVD technology a high-speed deposition line exceeding the present limit of 200 m/min set by conventional EG & HDG lines due to physical limitations, numerous developments were necessary.
An overview of these developments will be presented during the lecture, as well as the deployment of the JVD technology to other steelmakers worldwide through license agreements proposed by John Cockerill.
