Abstract (en)
[origin: WO2009021489A2] The invention relates to a process for producing an active anti-corrosion coating on steel components. In order to develop an active anti-corrosion coating which can be applied on an industrial scale using conventional means (e.g. dipping, spraying, flooding) and is intended for hot-formed and in particular press-hardened steel parts provided with anti-scaling means, the invention proposes a process comprising the following process steps: a. using a steel element provided with an anti-scaling layer, b. annealing the steel element at a temperature above 600°C in an annealing furnace for the purpose of hardening, semi-hot or hot forming or press-hardening, in which case a reaction layer is produced, and c. applying an anti-corrosion coating to the annealed reaction layer.
