Abstract: The present invention is related to a method for depositing a coating on a substrate (2) by a flame-assisted chemical vapour deposition technique, wherein the substrate is exposed to a flame produced by a burner (1), while a flow of precursor elements is added to said flame, and wherein the substrate is subjected to a relative movement with respect to said burner wherein the flame is dragged out along a reaction zone (3) situated behind the burner, and wherein the relative speed of the substrate with respect to the flame is higher than 30 m/min.

Abstract: The present invention is related to a method for the production of metal coated steel products including steps of: providing a steel product with a metal coating; adding an additional metallic element to the metal coating; subjecting the metal coated steel product to a thermal treatment. The method is characterized in that: prior to the addition of the additional element, the steel product is subjected to a plasma treatment via a dielectric barrier discharge, for cleaning and activating the surface of the metal coating; the additional element is added through a physical vapor deposition technique; the thermal treatment is applied by directing high energy infra red radiation towards the outer surface of the metal coating.
