Definitions

  • the invention relates to a method for phosphating metal surfaces with aqueous, acid phosphating solutions containing zinc, manganese and phosphate ions and oxidizing agents, and to its use as a pretreatment of the metal surfaces for subsequent painting, in particular electro-dip painting, and for the phosphating of steel.
  • phosphating of metals pursues the goal of creating firmly adherent metal phosphate layers on the metal surface, which in themselves improve the corrosion resistance and, in conjunction with lacquers and other organic coatings, contribute to a significant increase in adhesion and resistance to infiltration when exposed to corrosion.
  • phosphate layers serve as insulation against the passage of electrical currents and in connection with lubricants to facilitate sliding processes.
  • the low-zinc phosphating processes are particularly suitable, in which the phosphating solutions have comparatively low zinc ion contents of e.g. B. 0.5 to 1.5 g / l.
  • the phosphating solutions have comparatively low zinc ion contents of e.g. B. 0.5 to 1.5 g / l.
  • phosphate layers with a high content of phosphophyllite (Zn2Fe (PO4) 2.4H2O) are produced on steel, which is considerably more corrosion-resistant than the hopite (Zn3 (PO4) 2.4H2O) deposited from zinc-rich phosphating solutions.
  • Zn3 (PO4) 2.4H2O hopite
  • the high content of nickel ions in the phosphating solutions of the trication processes and of Ni and Ni compounds in the phosphate layers formed has disadvantages insofar as nickel and nickel compounds are to be classified as hazardous from the point of view of workplace hygiene and environmental protection.
  • the object of the invention is to provide a process for the phosphating of metals, in particular steel, galvanized steel, alloy-galvanized steel and aluminum and its alloys, which leads to phosphate layers, the quality of which roughly corresponds to the layers of the trication process based on Zn-Mn Ni corresponds without having the disadvantage of the presence of Ni and Ni compounds.
  • the object is achieved by designing the method of the type mentioned at the outset in accordance with the invention in such a way that the metal surfaces are brought into contact with phosphating solutions which are essentially free of nickel, the 0.3 to 1.7 g / l Zn 0.2 to 4.0 g / l Mn 0.001 to 0.030 g / l Cu 5 to 30 g / l phosphate (calculated as P2O5) contain and in which the concentration of Fe (II) is kept below 0.1 g / l and the pH is adjusted to 3.0 to 3.8 by means of oxygen and / or other oxidizing agents having the same effect.
  • the method according to the invention is applied in particular to steel, galvanized steel, alloy-galvanized steel, aluminum and its alloys.
  • steel includes soft unalloyed steels, high and high-strength steels (e.g. microalloyed, dual-phase and phosphorus alloyed) and low-alloyed steels.
  • the galvanizing layers can e.g. B. generated by electrolysis, hot dipping or vapor deposition.
  • Typical zinc qualities include pure zinc and z.
  • Aluminum and aluminum alloys are understood to mean the casting and kneading materials used in the metal industry, which can contain, for example, Mg, Mn, Cu, Si, Zn, Fe, Cr, Ni, Ti as alloying elements.
  • the basic requirement of the process according to the invention is that the aqueous, acidic phosphating solutions are essentially free of nickel. This means that under technical conditions the Ni concentration in the phosphating baths is less than 0.0002 to 0.01 g / l. However, it is preferably below 0.0001 g / l.
  • the essential content of the invention is also the presence of the three metal cations Zn, Mn and Cu in the amounts indicated.
  • Zn concentrations below 0.3 g / l lead to a significant deterioration in the layer formation, particularly when treating steel.
  • the phosphophyllite content in phosphate layers on steel drops sharply, at the same time the quality of the phosphate layers in connection with painting is reduced.
  • Below 0.2 g / l Mn the addition of this cation has no visible advantages, above a concentration of 4 g / l there are no further improvements in quality observe.
  • the Cu concentration is between 0.001 and 0.030 g / l. Below this range, the favorable effect on layer formation and layer quality is lost, while above 0.030 g / l Cu an annoying Cu cementation becomes increasingly noticeable.
  • Fe dissolves in the form of Fe (II) ions.
  • the phosphating bath must now contain so much oxygen and / or other oxidizing agents that the stationary Fe (II) ion concentration does not exceed a value of 0.1 g / l, i.e. H. that all other Fe is converted into Fe (III) and precipitated as iron phosphate sludge.
  • the pH value of the phosphating solution must be adjusted to a value between 3.0 and 3.8.
  • the higher (lower) pH values apply to lower (higher) bath temperatures and to lower (higher) bath concentrations.
  • additional cations e.g. B. alkali (Na, K, NH4 and others), and / or alkaline earth metal ions (Mg, Ca) or other anions (NO3, Cl, SiF6, SO4, BF4 and others) also used.
  • the quality of the phosphate layers produced with the aid of the method according to the invention can be improved if up to 3 g / l Mg and / or up to 3 g / l Ca are added to the phosphating solution.
  • the preferred concentration range for these cations is 0.4 to 1.3 g / l each.
  • the cations can e.g. B. as phosphate or as a salt with the above mentioned anions are introduced into the phosphating solution.
  • the oxides, hydroxides and carbonates are also suitable as a source of Mg and Ca.
  • the Zn concentration is preferably 0.3 to 1 g / l, while for the spraying / dipping and dipping method the Zn content in the bath is preferably 0.9 to 1.7 g / l is set.
  • the preferred Mn concentration is - regardless of the type of application - between 0.4 and 1.3 g / l.
  • the metal surfaces are brought into contact with a phosphating solution which contains 0.003 and 0.020 g / l Cu. Furthermore, particularly favorable phosphating results are achieved if the weight ratio between Cu and phosphate, calculated as P2O5, is 1: (170 to 30,000) in the phosphating bath and Cu and P2O5 are supplemented in a weight ratio of 1: (5 to 2000).
  • the preferred oxidizing agents include nitrite, chlorate, bromate, peroxy compounds (H2O2, perborate, percarbonate, perphosphate, etc.) and organic nitro compounds, eg. B. nitrobenzenesulfonates. These oxidizing agents can be used alone or in combination - if appropriate also with weaker oxidizing agents such as nitrate. Suitable combinations are e.g. B.
  • oxidizing agents mentioned not only serve to oxidize Fe-II ions, but also accelerate them Phosphate layer formation. Examples of typical concentration ranges for the oxidizing agents mentioned in the phosphating bath are given below.
  • Nitrite 0.04 to 0.5 g / l; Chlorate: 0.5 to 5 g / l; Bromate: 0.3 to 4 g / l; Peroxy compound, calculated as H2O2: 0.005 to 0.1 g / l; Nitrobenzenesulfonate: 0.05 to 1 g / l.
  • a further preferred embodiment of the invention consists in bringing the metal surfaces into contact with phosphating solutions which additionally contain compounds with a modifying action from the group of surfactants, hydroxycarboxylic acid, tartrate, citrate, single fluoride, boron fluoride, silicon fluoride.
  • surfactant e.g. 0.05 to 0.5 g / l
  • Hydroxyarboxylic acids e.g. B. tartaric acid, citric acid or its salts lead in the concentration range of z. B. 0.03 to 0.3 g / l to a significant reduction in the weight of the phosphate layer.
  • Single fluoride favors the phosphating of metals which are more difficult to attack and leads to a shortening of the minimum phosphating time and an increase in the area coverage of the phosphate layer.
  • z. B. F contents of 0.1 to 1 g / l.
  • the controlled addition of single fluoride also enables the formation of crystalline phosphate layers on aluminum and its alloys.
  • BF4 and SiF6 also increase the aggressiveness of the phosphating baths, which is particularly evident when treating hot-dip galvanized surfaces. These additives are used, for example, in amounts of 0.4 to 3 g / l.
  • the phosphating process according to the invention is suitable for use in spraying, spraying / dipping and dipping.
  • the bath temperatures are usually between 40 and 60 ° C.
  • exposure times of e.g. B. 1 to 5 min sufficient to deposit evenly covering phosphate layers.
  • contact times of less than 10 seconds are often sufficient for galvanized steel, so that the method can also be used in high-speed conveyor systems.
  • the surfaces are usually cleaned, rinsed and often treated with activating agents based on titanium phosphate before they are brought into contact with the phosphating solution.
  • the phosphate layers produced with the phosphating process according to the invention are finely crystalline and uniformly opaque.
  • the weight per unit area is usually between 1.5 and 4.5 g / m2 for the treatment of steel, galvanized steel and alloy-galvanized steel and between 0.5 and 2.5 g / m2 for the treatment of aluminum and its alloys.
  • the phosphating solution e.g. B. by incorporation into the phosphate layer, by sludge formation, by mechanical bath losses over the treated metal surface and the sludge discharge, by redox reactions and also by decomposition. For this reason, the phosphating solution must be monitored analytically and supplemented with the missing components.
  • the phosphate layers can, among other things, be used advantageously for corrosion protection, for facilitating non-cutting cold forming and for electrical insulation. However, they are preferably used to prepare metal surfaces for painting, in particular electrocoating, with particularly good results in connection with cathodic electrocoating be achieved. Before painting, it is recommended that the phosphate layers with passivating detergents such. B. based on Cr (VI), Cr (VI) -Cr (III), Cr (III), Cr (III) fluorozirconate, Al (III), Al (III) fluorozirconate. This further increases paint adhesion and infiltration resistance.
  • Sheets made of steel, galvanized steel and aluminum were degreased with an alkaline cleaner, rinsed with water and, if necessary after phosphating with a solution containing titanium phosphate, phosphated with the phosphating solutions 1 to 12 at 50 ° C. In all cases, uniformly covering phosphate layers were produced, which in connection with cathodic electrocoat + automotive paint build-up provided good paint adhesion and good resistance to corrosion penetration.
