| 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 a 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. |
