Definitions
- the invention relates to a method for applying phosphate coatings on surfaces made of aluminum and / or zinc or its or their alloys with the aid of phosphating solutions which operate according to the low zinc technology 0.4 to 1.5 g / l zinc and 10 to 16 g / l P2O5 contain,
- phosphating solutions that work according to the low-zinc technology are those that predominantly contain zinc as a layer-forming cation in a concentration of approx. 0.4 to 1.5 g / l and in which the Zn / PO4 ratio is less than approx. Is 0.08.
- phosphating solutions used for this usually contain zinc, nickel, manganese, magnesium, cadmium, copper, cobalt, alkali and / or ammonium ions, phosphate ions, accelerating additives such as nitrite, chlorate, bromate, peroxide, m -Nitrobenzenesulfonate, nitrophenol or combinations thereof.
- accelerating additives such as nitrite, chlorate, bromate, peroxide, m -Nitrobenzenesulfonate, nitrophenol or combinations thereof.
- aluminum, its alloys and galvanized steel they preferably additionally contain simple and / or complex fluorides.
- the phosphating solutions can also contain layer-refining additives, such as hydroxy carboxylic acids, amino carboxylic acids or condensed phosphates.
- the metal surfaces consist to a large extent of steel in addition to varying amounts of galvanized steel and a small amount of aluminum materials and are treated by spraying and / or immersion.
- the object of the invention is to provide a method for applying phosphate coatings on surfaces made of zinc and / or aluminum or its alloys with phosphating solutions working according to the low zinc technology, in which an increase in the free acid or the acid ratio is prevented and consequently, the disadvantages of the known methods are avoided, which is nevertheless easy to use and economical.
- 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 surface is brought into contact with a phosphating solution which contains a minimum concentration of iron (III) ions of 1 mg / l and which is treated per m2 Surface 50 to 2000 mg of iron III ions can be added.
- the iron ions can be introduced into the phosphating solution in the form of Fe-III ions, but also in the form of Fe-II ions together with an oxidizing agent, such as chlorate, nitrite, peroxide, which oxidizes to Fe-III.
- Suitable compounds are e.g. the nitrates, chlorides and fluorides of divalent or trivalent iron and iron-III complex compounds of hydroxy carboxylic acids, aminocarboxylic acids and the like.
- a preferred embodiment of the invention consists in bringing the surface into contact with a phosphating solution, to which 50 to 1000 mg of iron III ions are added per m2 of treated surface.
- the dosage can take place as mentioned above.
- such solutions are used that up to 1.3 g / l Ni up to 1.3 g / l Mn up to 1.3 g / l Mg contain.
- the weight ratio of Ni, Mn and or Mg to Zn should be set to a value of up to 1.5: 1.
- phosphating solutions which act as accelerators 2 to 25 g / l NO3 1 to 6 g / l ClO3 0.1 to 2 g / l organic nitro compound 0.05 to 0.5 g / l NO2 0.02 to 0.1 g / l peroxide (calculated as H2O2) or mixtures thereof.
- the phosphating solutions can be applied in a conventional manner. Particularly suitable forms of application are spraying and / or dipping, a temperature in the range from 30 to 70 ° C. being preferred.
- the method according to the invention is particularly suitable for the treatment of pure aluminum and alloys, e.g. of the qualities AlMgSi, AlMg and AlMgMn.
- Suitable materials are also solid zinc alloys or steel alloys with e.g. Ni, Fe or Al.
- iron III citrate By adding iron III citrate, the iron III concentration had been adjusted to 2 mg / l when the phosphating solution was started up.
- iron III citrate (calc. As Fe) was added to the phosphating solution of 10 l of 250 mg / m 2 surface.
- the number of free acid points was practically constant.
- the phosphate coating obtained was consistently uniform and closed.
