Abstract
There is a constant drive to improve automobiles by enhancing safety, reducing weight and containing cost. This, combined with a new focus on resource efficiency during manufacturing, forces role players to rethink and improve current processes and to develop novel manufacturing techniques. One such novel resource saving technique, currently being researched at the Chemnitz University of Technology and Fraunhofer IWU, combines a modified batch galvanizing process with a direct hot stamping process. In doing so it eliminates the tradetionally required surface coating process with its energy requirements. In this study the process uses molten zinc alloy at 850 °C to simultaneously heat and apply a corrosion protective coating to 22MnB5 for subsequent use in hot stamping. A CFX simulation was conducted in order to understand the thermal behaviour of the bath containing the alloy and the treated steel during the dipping process.
