Definitions
- the steel flat product coated with two layers in this way is then heated to a hot-forming temperature which is at least 750° C.
- a base layer is formed alloyed from Al, Fe, Zn and Si, in which the greatest proportion is Al, but Fe, Zn and Si also emerge as significant constituents.
- hot-forming temperatures of 850-950° C., in particular 850-900° C. are typically set.
- steel flat product coated in the way according to the invention can be formed without any difficulty into a steel component.
- steel flat product coated according to the invention has proved itself suitable both for a direct hot-forming operation, i.e. carried out as a single-stage production step without the preceding cold-deformation, and for an indirect, i.e. at least two-stage, forming operation characterised by cold deformation followed by hot deformation.
- a zinc-alloyed surface having a zinc content of at least 60% wt., in particular at least 80% wt. is present.
- Cathodic corrosion protection results from this, which can be proved electrochemically in unequivocal terms.
- salt spray test it can be proved that coatings produced according to the invention have a resistance to corrosion which are comparable to pure zinc coatings.
- the Al coating applied onto the steel flat product has a thickness of 5-25 ⁇ m, in particular 5-15 ⁇ m, and if the Zn coating applied onto the AlSi coating, before heating to the hot-forming temperature, has a thickness of 2-10 ⁇ m.
- Tests have shown thereby that, especially if the AlSi coating is applied by hot-dip aluminising, before heating to the hot-forming temperature a 2-5 ⁇ m thick alloy barrier layer containing Al, Si and Fe is present between the steel flat product and the correspondingly applied AlSi coating.
- a metallic coating applied according to the invention in two production steps onto the flat product to be deformed typically has a total thickness of 7-35 ⁇ m.
- FIG. 3 a schematic illustration of a third process flow according to the invention during coating of a steel flat product
- FIG. 5 a schematic illustration of a fifth process flow according to the invention during coating of a steel flat product
- the production steps cleaning, hot-dip aluminising (i.e.: annealing, conveying through an AlSi hot-dip bath), skin-pass rolling and electrolytic coating are completed in a sequence of operations which are performed continuously.
- a steel strip consisting of a temperable steel having a carbon content of 0.22%, an Mn content of 1.2%, a Cr content of 0.20% and a B content of 0.003% was annealed as a cold-rolled strip in a way known per se in a continuous hot-dip coating line and coated with an AlSi melt.
- the strip was firstly cleansed in a cleaning section of the dirt residues from the cold-rolling process and then passed through an annealing oven as it was heated to 750° C.
- the strip After cooling to a temperature of 680° C. (also still under protective gas 10% H 2 , remainder N 2 ) the strip entered an aluminium bath having a temperature of 660° C. In addition to Al, the aluminium bath also contained approx. 10% wt. silicon.
- the strip was firstly given an alkaline cleaning, so that it could be subsequently coated with a zinc coating of 3 ⁇ m in a PVD module. Finally, the strip was wound into a finished coil.
- Corrosion protection properties could also be substantiated for the component obtained in such a way, which corresponded to the properties which were determined for the component produced according to Test 1.
