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. The present invention is further related to an apparatus including: a component for performing a plasma treatment on a metal coated product; a component for adding an additional element to the metal coating by using a physical vapor deposition technique; a component for directing high energy infra red radiation towards the outer surface of the metal coating.
