摘要:
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 that can be applied on an industrial scale using conventional means (e.g. dipping, spraying or flooding) and is intended for hot-formed and, in particular, press-hardened steel parts provided with antiscaling means, the invention proposes a process comprising the following process steps: a. Using a steel element provided with an antiscaling 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 and thus producing a reaction layer; c. Applying an anti-corrosion coating to the annealed reaction layer.

The invention relates to a method for producing deformable corrosion protection layers on a metallic surface and to use of the method. In order to create an economical process for cathodic corrosion protection of metal for a broad range of applications, the invention proposes a method for producing deformable corrosion protection lavers on a metallic surface, consisting of the following steps: a) Mixing 5 to 95 wt. % metallic magnesium, zinc, aluminum or titanium particles, or mixtures or alloys containing at least one of these metals, in the form of pigments, powders, pastes (flakes) or pellets with 5 to 95 wt. % of at least one metal compound, wherein a reaction between the metal particles and metal compound(s) results in surface-modified metal particles; b) Applying the resulting surface-modified metal particles to the metallic surface; c) Hardening the layer produced from the surface-modified metal particles at temperatures between room temperature and 350° C. It has been shown within the context of the invention that the metal substrate coated according to the method of the invention can be deformed, overpainted, welded, coated and colored, and reflects heat.
