Definitions
- the invention relates to a process for the surface treatment of a metallic substrate, in particular steel sheet, with a Zn-based protective coating, in which a chloride-containing solution is applied to this protective coating, thereby forming, at least in some areas, a corrosion protection layer comprising hydrozincite and Simonkolleit.
- WO2012 / 091385A2 proposes to adjust the weight ratios of Al and Mg in the Zn-based protective coating so that the formation of Simonkolleit facilitates corrosion. It is proposed that in the protective coating the quotients of Al to (Mg + Al) should be in a range of 0.38 to 0.48. Disadvantageously, however, such compositional provisions cause a relatively high outlay, in particular when protective coatings are to be applied to a metal sheet with the aid of a hot-dip method - the reproducibility of the method is therefore difficult to ensure. In addition, such regulations usually lead only to a compromise between on the one hand improved corrosion behavior on the one hand and undesirable changes in mechanical, chemical and / or electrical properties on the other hand. The usability of the thus protective coated sheet can be significantly limited.
- JP 01 127683A, JP 04165082A and JP 201 1 168855A show, for steel sheets, coatings containing Zn, Mg and / or Al.
- the invention is therefore based on the object, starting from the above-described prior art, a method for surface treatment of a Zn-based protective coated sheet to change such that the corrosion resistance increases, reduces their fluctuation and its production is accelerated.
- a high reproducibility of the method should be ensured and the method be applicable regardless of the composition of the protective coating Zn-based.
- the invention achieves the stated object in that the protective-coated substrate with the, with the aid of an acid to a pH in the range of 4 to 6 set and a 1, 8 to 18.5 wt .-% chloride solution for forming a compared to the Hydrozinkitanteil increased Simonkolleitanteils in the anticorrosion layer reacts.
- this solution according to the invention in particular also water-based, can considerably promote the formation of monolithic collagen on the treated or corroded surface of the protective coating.
- the composition of the anticorrosion layer can be influenced in such a way that it always forms a higher Simonkolleitanteil compared to the Hydrozinkitanteil increased. This can certainly be expected with a high corrosion resistance of the protective coated substrate.
- this directional treatment or corroding of the protective coating can be carried out independently of the composition of a Zn-based protective coating - that is, any compositions can be improved in corrosion resistance.
- a universally applicable and reproducible method can thus be made available, in which the influence of a hot dip method on corrosion resistance or its range of variation with respect to the layer thickness of their patency and composition can be significantly reduced.
- the method according to the invention can be distinguished for increasing the corrosion resistance, if the protective coating has a Zn-Al-Mg base, to which the chloride having solution applied and thereby at least partially a corrosion protection layer, comprising Hydrozinkit, Simonkolleit and Hydrotalcit is formed.
- a corrosion protection layer comprising hydrozincite, Simonkolleit and Hydrotalcit, train.
- Their corrosion-susceptible and superficial intermetallic phases can be supplemented with Simonkolleit namely and corrosion-resistant.
- this formed a comparatively compact surface coating which in turn can lead to increased mechanical strength of the protective coating.
- the improved bondability achieved by this for further layers for example paints or the like, can be used on this protective coating.
- the production of the improved corrosion resistance in the protective coating is accelerated and thus the process can be carried out comparatively quickly.
- a solution which has 5 to 30% by weight of NaCl has proved particularly advantageous. This is not only inexpensive and easy to manufacture, it also has positive process engineering influence. Particularly well, 5 to 10 wt .-% NaCl may be suitable to provide a sufficiently high for the process chloride content in the solution.
- the solution applied to the protective coating consists of water, NaCl and HCl.
- this solution may also have production-related unavoidable impurities.
- This solution which was easy to prepare, proved to be particularly advantageous in the reaction with a Zn-Al-Mg protective coating, in which a proportion of Simonkolleit of more than 80% formed in the treated areas of the protective coating. A comparatively high proportion of Simonkolleit can be ensured by the solution reacting with the coating for a maximum of 20 minutes. Even with this relatively short reaction time, the method according to the invention can ensure a particularly rapid process and, subsequently, also be suitable for industrial purposes.
- reaction time of the solution with the protective coating can be further reduced if the metallic substrate is anodically charged in the reaction with the solution.
- the temperature of the solution is adjusted to a range of 30 to 60 degrees Celsius, the training of Simonkolleit can be fostered, thus further speeding up the process.
- the invention can be distinguished in particular by Zn-based protective coatings which are applied to the metal sheet by means of a hot-dip process - ie produced on the metal sheet.
- Known parameter fluctuations of the hot dip process which can have an influence on the corrosion resistance of the protective coating formed therewith, can thus be compensated for.
- the method according to the invention can therefore ensure particularly highly reproducible corrosion protection on sheets.
- reaction of the solution with the protective coating forms a corrosion protection layer with a layer thickness in the range of 150 nm to 1.5 ⁇ m, a sufficiently compact reaction layer with simonollector can be obtained in order to reproducibly increase the corrosion resistance of the protective-coated substrate.
- the chemical resistance of the Zn-based protective coating can be further increased if the reaction of the solution with the protective coating has a corrosive effect. rosionstik für with a share of at least 80%, in particular of at least 90%, Simonkolleit trains.
- the method according to the invention can be distinguished in particular with a Zn-Al-Mg protective coating in which the quotient of Al / (Al + Mg) is in the range from 0.5 to 1.0, in particular if the quotient of Al / (Al + Mg) is 0.5.
- the tested protective coated steel sheets are shown in Table 1.
- Table 1 Overview of the examined protective coated steel sheets 1, 2, 3
- the protective coated sheets treated with the solution according to the invention each exhibited compact anticorrosive layers with layer thicknesses in the range from 150 nm to 1.5 ⁇ m.
- An increased corrosion resistance of the Zn-Al-Mg protective coating could be achieved in the protective coated steel sheet 2 already after 10 minutes and a temperature of the solution in the amount of 30 degrees Celsius, wherein in the reaction of the solution with the protective coating anodic load (20V, 50Am " 2 ) was created.
- the same increased corrosion resistance of the Zn-Al-Mg protective coating could be achieved in the protective coated steel sheet 3 after 20 minutes and a solution temperature of 60 degrees Celsius. Anodic loading of the protective coating could be dispensed with here.
