Definitions
- the invention relates to a process for the production of phosphate coatings on at least partially iron or steel surfaces having individual parts made of metal by means of aqueous phosphating solutions which contain zinc, phosphate, nitrate and autocatalytically formed nitrite ions and are practically free of iron II ions.
- Another type of zinc phosphate process which usually works with high nitrate contents and at higher temperatures, is characterized in that the phosphating solutions used are practically free of iron II ions. In them, nitrite, which contains the iron II ions, forms autocatalytically Iron III ions are transferred, which in turn form poorly soluble iron phosphate with phosphate ions (DE-A-25 40 684).
- the object of the invention is to provide a method for producing phosphate coatings on at least partially iron or steel surfaces having individual parts, which does not have the disadvantage of the long treatment time, but leads in a short time to phosphate coatings which are nevertheless of high quality.
- 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 individual parts are in contact with a phosphating solution at a temperature in the range from 60 to 100 ° C. for a period of 3 to 30 seconds brings that 10 to 80 g / l zinc 12 to 80 g / l Phosphate (calculated as P2O5) 40 to 150 g / l Nitrate as well as additional 0.1 to 5 g / l fluoride 0.01 to 10 g / l nickel 0.001 to 0.1 g / l copper contains, in which the ratio of free acid to total acid is set to (0.1 to 0.3): 1 and which has at least 80 points total acid.
- nitrite is formed autocatalytically, it may be necessary to add nitrite to the phosphating solution, for example in an amount of 0.03 to 0.2 g / l, in the initial phase of the process.
- the method according to the invention is used in particular for the treatment of individual parts whose iron or steel surface has alloy additions of up to a maximum of 5% by weight.
- the individual components of the phosphating solution such as zinc, phosphate, nitrate, etc.
- the individual components are usually, as is customary in phosphating technology, pre-dissolved together as an acidic phosphating concentrate and introduced into the phosphating solution in this form.
- the individual components are dimensioned in such a way that the required concentration ranges result in the phosphating solution.
- additional cations from the alkali and / or ammonium group may have to be used.
- titrate 10 ml bath sample with n / 10 NaOH against the first or second change in phosphoric acid using the color change of dimethyl yellow (free acid) or phenolphthalein (total acid), for example, as an indicator.
- the ml of n / 10 NaOH consumed correspond to the free acid or the total acid in points.
- the content of nitrite points is usually determined using the saccharometer method. For this, 50 ml of bath solution are mixed with 2 to 5 g of sulfamic acid. The amount of gas generated in ml is equal to the number of points. A gas point corresponds to a content of 46 mg / l NO2 in the phosphating solution.
- the contact of the individual parts with the phosphating solution is preferably carried out by dipping or flooding.
- the phosphate coatings produced by the process according to the invention have a layer weight of 2.0 to 10 g / m2.
- a preferred embodiment of the invention consists in bringing the individual parts into contact with a phosphating solution 30 to 60 g / l zinc 30 to 50 g / l Phosphate (calculated as P2O5) 65 to 100 g / l nitrate 0.5 to 3.0 g / l Fluoride and 0.02 to 0.5 g / l nickel contains.
- the rate of formation of the phosphate coating can be increased if, in accordance with a further advantageous embodiment of the invention, the individual parts are brought into contact with a phosphating solution which contains further accelerating additives.
- accelerating additives can be, for example, chlorate, bromate, peroxide, m-nitrobenzenesulfonate, nitrophenol or combinations thereof.
- a further improvement in the properties of the phosphate coating can be achieved if, according to a further advantageous embodiment of the invention, the individual parts are brought into contact with a phosphating solution which contains an additional 0.1 to 10 g / l, preferably 1 to 5 g / l, of manganese.
- a phosphating solution which additionally contains 0.05 to 3 g / l tartaric acid and / or citric acid.
- Another advantageous embodiment of the invention is to clean the individual parts before phosphating, if necessary to free them of rust, scale and phosphate layer and to activate them, and to passivate them with a rinse solution after phosphating, each of the process steps lasting from 3 to 30 sec is carried out.
- an alkaline cleaning solution at a temperature in the range between 60 and 100 ° C. and a concentration in the range from 20 to 200 g / l for cleaning.
- cleaners those based on sodium hydroxide, gluconate, phosphate with an additional content of carbonate, silicate and borate and surfactant.
- the cleaner is preferably used in spraying.
- Sulfuric acid or phosphoric acid solutions at a temperature in the range from 60 to 100 ° C. and a concentration in the range from 5 to 50% by weight have proven to be advantageous for the removal of rust, scale and phosphate layers that may be required.
- a sulfuric or phosphoric acid is used which additionally contains iron II and / or iron III ions in a concentration in the range from 1 to 50 g / l.
- the phosphating treatment After the phosphating treatment, it is usually rinsed with water, rinsed if necessary and dried if necessary.
- a further advantageous embodiment of the invention provides for the individual parts to be passivated with a chrome-containing or chrome-free rinse solution. Possibly. can also be treated with an emulsion of an anti-corrosion oil, or it can be painted with or without passivation. In the event that cold forming is intended, an aftertreatment with a soap bath can also be carried out.
- the phosphate coatings produced by the process according to the invention can be used advantageously in all fields in which phosphate coatings are used.
- the phosphating process according to the invention is particularly favorable in improving the corrosion protection in the case of a subsequent painting.
- the phosphate coating produced after this operation had a basis weight of 4 to 5 g / m2.
- the phosphate coating was uniformly opaque and fine crystalline.
