Definitions
- the invention relates to a method for the surface treatment of a metallic substrate, in particular steel sheet, with a protective coating based on Zn, in which a chloride-containing solution is applied to this protective coating and thereby a corrosion protection layer comprising hydrozincite and simoncollect is formed at least in some areas.
- WO2012 / 091385A2 propose to set the weight ratios of Al and Mg in the protective coating based on Zn so that the formation of Simonkolleit is easier in the event of corrosion. It is proposed that the protective coating should have a ratio of Al to (Mg + Al) in a range from 0.38 to 0.48.
- compositional regulations disadvantageously cause a comparatively high outlay, in particular if protective coatings are to be applied to a metal sheet by means of a hot-dip process - the reproducibility of the process is therefore difficult to ensure.
- such regulations mostly only lead to a compromise between improved corrosion behavior on the one hand and undesirable changes in mechanical, chemical and / or electrical properties on the other. The usability of the sheet coated in this way can be significantly restricted.
- JP 01127683A the JP 04165082A and the JP 2011168855A for steel sheets, coatings containing Zn, Mg and / or Al.
- the invention is therefore based on the task, starting from the prior art described at the outset, of changing a method for surface treatment of a sheet coated with a protective layer based on Zn in such a way that the corrosion resistance is increased, the range of fluctuation is reduced and its production is accelerated.
- a high reproducibility of the process should be ensured and the process should be applicable regardless of the composition of the protective coating based on Zn.
- the invention solves the problem set by the process features of claim 1, wherein the protective coated substrate with the, adjusted with the aid of an acid to a pH in the range of 4 to 6 and having 1.8 to 18.5 wt .-% chloride Solution to form an increased proportion of Simonzolleitreact in the corrosion protection layer compared to the hydrozincite.
- Preferred embodiments of the method are defined in claims 2 to 10.
- the protective-coated substrate reacts with the solution which has been adjusted to a pH in the range from 4 to 6 and has from 1.8 to 18.5% by weight of chloride with the aid of an acid, a particularly advantageous corrosion protection layer can be achieved on the protective coating .
- This solution according to the invention in particular also water-based, can considerably favor the formation of Simonkolleit on the treated or corroded surface of the protective coating.
- the composition of the anticorrosive layer can be influenced in one direction in such a way that an increased proportion of Simoncollegium compared to the hydrozincite fraction. This means that the protective-coated substrate can be expected to be highly resistant to corrosion.
- this directional treatment or corrosion of the protective coating can be carried out independently of the composition of a protective coating based on Zn - any compositions can therefore be improved with regard to their corrosion resistance.
- a universally applicable and reproducible process can therefore be made available in which the influence of a hot-dip process on corrosion resistance or its fluctuation range with regard to the layer thickness, its continuity and composition can be significantly reduced.
- the method according to the invention for increasing the corrosion resistance can be distinguished in particular if the protective coating has a Zn-Al-Mg base to which the chloride-containing solution is applied and thereby at least in some areas a corrosion protection layer comprising hydrozincite, simoncollect and hydrotalcite is formed.
- a corrosion protection layer comprising hydrozincite, simoncolleite and hydrotalcite.
- Their corrosion-prone and superficial intermetallic phases can be supplemented with Simonkolleit and become more corrosion-resistant. This also resulted in a comparatively compact surface coating, which in turn can lead to increased mechanical strength of the protective coating.
- the improved connectivity achieved in this way can be used for further layers, for example lacquers or the like, on this protective coating.
- the production of the protective coating which is improved in corrosion resistance, is accelerated and the process can therefore be carried out comparatively quickly.
- a solution which has 5 to 30% by weight NaCl has proven to be particularly advantageous. This is not only inexpensive and easy to manufacture, it also has a positive procedural influence. 5 to 10% by weight of NaCl can be particularly suitable in order to ensure a sufficiently high proportion of chloride in the solution for the process.
- the solution applied to the protective coating consists of water, NaCl and HCl.
- this solution can also have inevitable impurities due to the manufacturing process.
- This solution which was easy to manufacture, was found to be particularly advantageous in the reaction with a Zn-Al-Mg protective coating, in which a proportion of Simonkolleit of over 80% was 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 fast process and can subsequently also be used for industrial purposes.
- reaction time of the solution with the protective coating can be reduced even further if the metallic substrate is anodically charged during the reaction with the solution.
- the formation of Simonkolleit can be favored and the process can be further accelerated.
- the invention can be particularly distinguished in the case of protective coatings based on Zn, which are applied to the sheet by means of a hot-dip process, that is to say produced on the sheet.
- Known parameter fluctuations in the hot-dip process which can influence the corrosion resistance of the protective coating formed with it, can thus be compensated for.
- the method according to the invention can therefore ensure the highest level of corrosion protection on metal sheets in a particularly reproducible manner.
- reaction of the solution with the protective coating forms a corrosion protection layer with a layer thickness in the range from 150 nm to 1.5 ⁇ m, a result in a sufficiently compact reaction layer with Simonkolleit in order to reproducibly increase the corrosion resistance of the protective-coated substrate.
- the chemical resistance of the protective coating based on Zn can be increased further if the reaction of the solution with the protective coating forms a corrosion protection layer with a proportion of at least 80%, in particular at least 90%, of Simonkolleit.
- the method according to the invention can be distinguished in particular in the case of 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.
- Table 1 Overview of the investigated protective coated steel sheets 1, 2, 3 Composition of the solution Simonkolleit Hydrozincite Hydrotalcite 1 no treatment undefined / variable 2nd 5% NaCl with a pH of 4-5 90% 5% 5% 3rd 10% NaCl with a pH of 5 90% 5% 5%
- the protective-coated sheets treated with the solution according to the invention each showed compact corrosion-protective layers with layer thicknesses in the range from 150 nm to 1.5 ⁇ m.
