Definitions
- the invention relates to a process for the production of phosphate coatings on metal surfaces of iron and steel using an acidic nitrate-accelerated zinc and manganese ion-containing phosphating solution at elevated temperatures in the immersion process.
- z. B. in the range between 8 to 30 g / m 2 required.
- particularly high demands are placed on corrosion protection. This can be achieved by increasing the layer weight.
- An increase in the layer weight would also allow higher degrees of deformation in cold forming.
- the deposition of thick zinc phosphate layers can according to DE-AS 12 87 412 and US Pat. No. 3,268,367 by bringing iron and steel into contact with a nitrate-accelerated acidic zinc phosphating solution with the addition of polycarboxylic acids in which the carbon atom adjacent to at least one carboxyl group is a hydroxy -, Amino or carboxyl group can be achieved.
- This phosphating solution can also contain additives such as nickel, cobalt, lithium, bismuth and manganese in small concentrations of less than 0.5 g / l. They activate the metal surface to be phosphated and promote the deposition of zinc phosphate layers.
- the object of the invention is to provide a phosphating process which does not have the disadvantages described, in particular is universally applicable, requires little chemicals and leads to higher-quality phosphate layers.
- 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 a phosphating solution which contains at least 0.6 g / l of manganese ions at treatment temperatures of 50 to 98 ° C. in which the weight ratio is and which has a total acid score of at least 20 points when incorporated.
- Such a method leads to zinc-manganese-phosphate layers which, with comparable layer thicknesses, are superior to zinc phosphate layers with regard to corrosion protection and cold-forming properties.
- the metal surfaces are preferably brought into contact with a phosphating solution in which the manganese ion content is at least 1 g / l.
- the metal surfaces are brought into contact with a phosphating solution in which the weight ratio of Mn: Zn is 1: (0.8 to 12).
- Manganese ion contents in the phosphating solution above the range of 1: 0.2 lead to non-closed, perforated layers.
- baths with e.g. 80 total acid points can be composed as follows:
- the total acid number can be determined by titration of a 10 ml bath sample with 0.1 N NaOH against phenolphthalein as an indicator until the color changes from colorless to pink.
- nickel and / or cobalt and / or copper ions and the like can be added to the bath.
- these metal ions in a concentration of z. B. 0.02 to 0.10 g / l added to the bath.
- the anion belonging to the metal ions can e.g. B. nitrate or sulfate.
- a phosphating solution which contains simple and / or complex fluorides, such as NaF, NaHF 2 and / or Na 2 SiF 6 .
- a certain reduction in the layer weight can be brought about if condensed phosphates are added to the phosphating bath.
- the workpieces to be phosphated should be free of grease, scale and rust.
- the degreasing can e.g. B. by means of aqueous, alkaline, surface-active substances containing cleaners.
- Descaling is advantageously carried out using sulfuric acid or hydrochloric acid.
- the workpieces After cleaning and / or pickling, the workpieces should be rinsed well with water.
- the workpieces can be formed in a manner known per se, e.g. B. with titanium orthophosphate or manganese orthophosphate suspensions in water. It has been found in practice that in some cases a pre-rinse with water at 50 to 98 ° C activates the surface.
- the phosphating bath is operated between 50 and 98 ° C depending on the type of workpiece, the alloy and the type of application. It has been shown that a diving time of 5 to 15 minutes is sufficient for most applications.
- iron II will accumulate in the phosphating bath in the course of the throughput. This does not affect the way the bath works. In special cases, e.g. B. at high nitrate concentrations or at high bath temperatures, it can also happen that the bath remains iron-II-free due to the oxidation of FeII to FeIII. This also does not affect the way the bath works.
- the addition of the bath is expediently carried out on a constant total acid number.
- the layer weight of the zinc-manganese-phosphate layers obtained is normally between about 5 and about 30 g / m 2, depending on the composition of the phosphating bath and the alloy of the workpiece to be treated.
- z. B. be treated with chromic acid solutions, followed by treatment with anti-corrosion oil emulsions.
- the workpieces can e.g. B. be treated with soap solutions.
- the workpieces treated in this way are superior to the workpieces treated with conventional nitrate accelerated zinc phosphating systems in terms of corrosion protection and cold forming properties.
- baths F and G The composition of baths F and G is shown in the following table.
- the total acid number of baths was 90 points each.
- sample sheets became branched off to determine the layer weight and for the corrosion test in the salt spray test according to DIN 50021 SS.
- the sheets for the corrosion test were previously treated with a 15% emulsion of an anti-corrosion oil and then dried in an oven at 70 ° C. It can be clearly seen that the preferred configuration of the supplement means that the phosphating baths, even after a throughput of 4 m 2 / l, lead to layers which have retained their good properties.
