Definitions
- the present invention relates to an improved process for essentially nickel-free phosphating of a metallic surface, a corresponding phosphating composition and a correspondingly phosphate-coated metallic surface.
- Such phosphate coatings are mainly used in the automotive industry and the general industry.
- KTL cathodically deposited electrodeposition paints
- phosphate coatings are usually applied by means of a nickel-containing phosphating solution.
- the elementary or as alloying constituent, e.g. Zn / Ni, deposited nickel ensures a suitable conductivity of the coating in the subsequent electrodeposition coating.
- nickel ions are no longer desirable as part of treatment solutions because of their high toxicity and environmental toxicity, and should therefore be avoided or at least reduced in content as much as possible.
- Another problem with nickel-free phosphating is to ensure adequate stability of the respective bath against parameter changes or the throughput of metallic substrates: Although the bath is initially free of mud or any turbidity. However, it turns cloudy after the first throughput of sheets, and eventually large amounts of sludge are formed. The parameters are not stable.
- the object of the present invention was therefore to provide a process with which metallic surfaces can be phosphated essentially nickel-free, wherein the aforementioned disadvantages of the prior art are avoided, and in particular a higher bath stability is achieved.
- a metallic surface is a metallic surface, optionally after purification and / or activation, with an acid aqueous, substantially nickel-free phosphating composition comprising zinc ions, manganese ions, iron (III) ions and phosphate ions, and thereafter optionally rinsed and / or dried.
- an uncoated metallic surface on the other hand, but also an already conversion coated metallic surface can be treated by the method according to the invention. If, in the following, a "metallic surface” is mentioned, therefore, an already conversion-coated metallic surface should always be included as well.
- aqueous composition refers to a composition which contains at least some, preferably predominantly water, as the solvent, and can also contain dispersed constituents, ie emulsified and / or suspended constituents include.
- Substantially nickel-free as used herein means that less than 0.3 g / l of nickel ion is contained.
- phosphate ions also means hydrogen phosphate, dihydrogen phosphate and phosphoric acid, and pyrophosphoric acid and polyphosphoric acid, as well as all their partially and completely deprotonated forms, are to be encompassed.
- metal ion is understood as meaning either a metal cation, a complex metal cation or a complex metal anion.
- the metallic surface is preferably steel, hot dip galvanizing, electrolytic galvanizing, aluminum or their alloys such as Zn / Fe or Zn / Mg.
- the metallic surface is at least partially galvanized in the case of hot-dip galvanizing and electrolytic galvanizing, The method according to the invention is particularly suitable for multi-metal applications.
- a metallic surface is to be coated, which is not a fresh hot-dip galvanizing, it is advantageous to clean the metallic surface before the treatment with the phosphating only in an aqueous cleaning composition, in particular to degrease.
- an acidic, neutral, alkaline or strongly alkaline cleaning composition it is possible in particular to use an acidic, neutral, alkaline or strongly alkaline cleaning composition, but optionally also an acidic or neutral pickling composition.
- An alkaline or strongly alkaline cleaning composition has proven to be particularly advantageous.
- the aqueous cleaning composition may optionally contain, in addition to at least one surfactant, a scaffold and / or other additives such as complexing agents.
- the use of an activating cleaner is also possible.
- After cleaning / pickling then takes place advantageously at least rinsing of the metallic surface with water, wherein the water optionally also dissolved in water additive such.
- As a nitrite or surfactant may be added.
- the activation composition serves to deposit a plurality of ultrafine phosphate particles as seed crystals on the metallic surface.
- acidic or alkaline compositions based on titanium phosphate or zinc phosphate may be considered as activating compositions.
- the acidic, aqueous, substantially nickel-free phosphating composition includes zinc ions, manganese ions, ferric ions and phosphate ions.
- the content of iron (III) ions achieves a sufficient stability of the phosphating composition to parameter changes or the throughput of metallic substrates.
- the content of iron (III) ions in the phosphating composition is preferably in the range from 1 to 200 mg / l, more preferably from 1 to 100 mg / l, more preferably from 5 to 100 mg / l, particularly preferably from 5 to 50 mg / L and most preferably from 5 to 20 mg / L.
- the iron (III) ions can be added to the phosphating composition, for example as nitrate, sulfate, citrate or tartrate. However, the iron (III) ions are preferably not added as nitrate, because too much nitrate adversely affects the coating composition: the manganese content of the layer formed is lower.
- iron (III) ions are added to the phosphating composition prior to the adjustment of the free acid (FS, see the remarks below), which is due to the fact that the precipitation of zinc salts is thereby reduced and thus the Bath stability increased.
- the phosphating composition may be obtained from a concentrate by dilution with a suitable solvent, preferably with water, by a factor of between 1 and 100, preferably between 5 and 50, and if necessary adding a pH modifying substance.
- the phosphating composition preferably comprises the following components in the following preferred and particularly preferred concentration ranges:
- a concentration in the range from 0.3 to 2.5 g / l has already been found to be advantageous with regard to the free fluoride, a concentration in the range from 10 to 250 mg / l.
- the complex fluoride is preferably tetrafluoroborate (BF " ) and / or hexafluorosilicate (SiF 6 2 ⁇ ).
- a content of complex fluoride and single fluoride, such as sodium fluoride, in the Phosphating composition of advantage is a content of complex fluoride and single fluoride, such as sodium fluoride, in the Phosphating composition of advantage.
- Al 3+ is a bad poison in phosphating systems and can be removed from the system by complexation with fluoride, eg as cryolite.
- fluoride eg as cryolite.
- Complex fluorides are added to the bath as a "fluoride buffer", as otherwise the fluoride content quickly falls off and coating no longer takes place.Fluoride thus promotes the formation of the phosphate layer and thus indirectly also improves paint adhesion and corrosion protection.Complex fluoride also helps on galvanized material, errors like to avoid specks.
- the phosphating composition preferably contains at least one accelerator selected from the group consisting of the following compounds in the following preferred and particularly preferred concentration ranges:
- a concentration in the range of 0.1 to 3.0 g / l has already been found to be advantageous with respect to the H2O2, a concentration in the range from 5 to 200 mg / l.
- the at least one accelerator is H2O2.
- the phosphating composition preferably contains less than 1 g / l, more preferably less than 0.5 g / l, more preferably less than 0.1 g / l and most preferably from 0.05 to 0.1 g / l of nitrate.
- the nitrate in the phosphating composition causes an additional acceleration of the layer formation reaction, which leads to lower coating weights but, above all, reduces the incorporation of manganese into the crystal. Is the manganese content the However, phosphate coating too low, this is at the expense of their alkali resistance.
- Alkali resistance in turn plays a crucial role in subsequent cathodic electrodeposition.
- an electrolytic splitting of water occurs at the substrate surface: Hydroxide ions are formed. This causes the pH at the interface of the substrate to increase. It is true that only then can the electrocoating be agglomerated and separated. However, the increased pH can also damage the crystalline phosphate layer.
- the phosphating composition preferably has a temperature in the range of 30 to 55 ° C.
- the phosphating composition can be characterized by the following preferred and particularly preferred parameter ranges:
- FS free acid
- FS (dil.) For free acid (diluted)
- GSF for total acid according to Fischer
- GS for total acid
- S value for acid value determined as follows:
- a suitable vessel for example a 300 ml Erlenmeyer flask. If the phosphating composition contains complex fluorides, 2-3 g of potassium chloride (KCl) are added to the sample. Then, using a pH meter and an electrode, it is titrated with 0.1 M NaOH to a pH of 3.6. The amount of 0.1 M NaOH consumed in ml per 10 ml of the phosphating composition gives the value of the free acid (FS) in points.
- a suitable vessel for example a 300 ml Erlenmeyer flask.
- KCl potassium chloride
- the free acid (diluted) 10 ml of the phosphating composition are pipetted into a suitable vessel, for example into a 300 ml Erlenmeyer flask. Subsequently, 150 ml of deionized water are added. Using a pH meter and an electrode, titrate with 0.1 M NaOH to a pH of 4.7. The consumed amount of 0.1 M NaOH in ml per 10 ml of the diluted phosphating composition gives the value of the free acid (diluted) (FS (dil.)) In points. About the difference to the free acid (FS) the content of complex fluoride can be determined. If this difference is multiplied by a factor of 0.36, the content of complex fluoride is SiF 6 2 ⁇ in g / l.
- the dilute phosphating composition is titrated to pH 8.9 after addition of potassium oxalate solution using a pH meter and electrode with 0.1 M NaOH.
- the consumption of 0.1 M NaOH in ml per 10 ml of the diluted phosphating composition hereby gives the total Fischer acid (GSF) in points. If this value is multiplied by 0.71, the total content of phosphate ions is calculated as P2O 5 (see W. Rausch: "The Phosphatization of Metals.” Eugen G. Leuze-Verlag 2005, 3rd edition, pp. 332 ff) ,
- the total acid (GS) is the sum of the divalent cations present as well as free and bound phosphoric acids (the latter being phosphates). It is determined by the consumption of 0.1 M NaOH using a pH meter and an electrode. For this purpose, 10 ml of the phosphating composition are pipetted into a suitable vessel, for example a 300 ml Erlenmeyer flask and diluted with 25 ml of deionized water. Then add 0.1 M NaOH to a pH Value of 9 titrated. The consumption in ml per 10 ml of the diluted phosphating composition corresponds to the total acid score (GS).
- S value stands for the ratio FS: GSF and is obtained by dividing the value of the free acid (FS) by the value of the total acid according to Fischer (GSF).
- a temperature of the phosphating of less than 45 ° C, preferably in the range between 35 and 45 ° C leads to further improved corrosion and paint adhesion values.
- the phosphating composition is essentially nickel free. It preferably contains less than 0.1 g / l and more preferably less than 0.01 g / l of nickel ions.
- the essentially nickel-free phosphating composition Due to the content of iron (III) ions, the essentially nickel-free phosphating composition has a significantly lower amount of sludge even after the repeated throughput of metallic substrates. Your parameters remain stable.
- iron (III) ions added to the phosphating composition also helps the electrochemical properties of essentially nickel-free phosphated metallic surfaces to be comparable or nearly comparable to those treated with nickel-containing phosphating solutions.
- iron (III) ions to the phosphating composition leads in particular to steel, galvanized steel and aluminum to a marked improvement in the paint adhesion and corrosion protection results.
- the phosphating composition is a conventional trication composition, ie it also contains at least zinc ions and manganese ions 0.3 g / l, preferably at least 0.5 g / l and particularly preferably at least 0.8 g / l of nickel ions.
- the treatment of the metallic surface with the phosphating composition is preferably carried out for 30 to 480, particularly preferably for 60 to 300 and very particularly preferably for 90 to 240 seconds, preferably by means of dipping or spraying.
- the following preferred and most preferred zinc phosphate layer weights are obtained on the metallic surface (determined by XRF, i.e. X-ray fluorescence analysis):
- the metallic surface which has already been treated with the phosphating composition is optionally rinsed and / or rinsed but then not treated with an aqueous Nach Wunschzusammen a, in particular not with one which comprises at least one kind of metal ions and / or at least one polymer.
- the already treated with the substantially nickel-free phosphating, ie phosphate-coated, metallic surface is optionally rinsed and / or dried, but then treated with an aqueous Nachêtzusammen a, especially not with such, which at least one type of metal ions and / or at least one polymer.
- an aqueous Nachêtzusammen a especially not with such, which at least one type of metal ions and / or at least one polymer.
- An electrocoating paint can then be cathodically deposited on the phosphate-coated metallic surface, and a coating system can be applied.
- the metallic surface is first rinsed, preferably with deionized water, and optionally dried.
