| titleOfInvention | Procedure for selective phosphating of a composite metal construction |
| abstract | Procedure for the chemical pretreatment -before the organic coating- of a composite metal construction containing at least a part of aluminum as well as at least a part of zinc and optionally a part of iron, in which this procedure (I) in a The first step involves the treatment of the composite metal construction with a zinc phosphate solution, which causes the formation of a crystalline zinc phosphate layer that completely covers the surface with a coating weight on the zinc and iron parts. range of 0.5 to 5 g / m2, but does not generate any zinc phosphate layer with a coating weight of at least 0.5 g / m2 on the aluminum parts and then with or without intermediate cycle of rinsing with water, (II) in a second step comprises the application of a treatment solution that has a pH value in the range of 3.5 to 5.5 on the composite metal construction, which detaches on the parts of zinc and iron no more than 50% of the crystalline zinc phosphate deposited in step (I), but forms a conversion layer on the aluminum parts, which does not represent any crystalline phosphate layer that completely covers the surface with a weight of a layer of at least 0.5 g / m2, the zinc phosphate solution in step (I) having a temperature in the range of 20 to 65 ° C and containing a quantity of free fluorides (measured in g / l) which is at least 0.005 g / l, but not greater than the quotient of number 8 and the solution temperature being in ° C (8 / T), with zinc phosphate solution being contained in at least 0.025 g / l, but less than 1 g / l of silicon in the form of water-soluble inorganic compounds calculated as SiF6 and not being the product (Si / mM) · (F / mM) of the concentration of silicon [Si in mM] in the form of compounds Water-soluble inorganic and free fluoride concentration [F in mM] divided by May free acid score r of 4.5, the free acid score in the zinc phosphate solution being at least 0.4 points, but not exceeding a value of 3.0 points. |
