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