摘要： The invention relates to a method for treating or pre-treating parts, profiled-pieces, strips, sheet metals and/or wires having metallic surfaces, in which at least 5% of these surfaces consists of aluminum and/or of at least one aluminum alloy and, optionally, the remaining metallic surfaces can predominantly consist of iron alloys, zinc and/or zinc alloys. The treatment involves the use of an acid aqueous solution, which contains fluoride, zinc and phosphate and which has the following dissolved contents in the phosphatizing solution: sodium virtually none or in a concentration ranging from 0.04 to less than 2 g/L; potassium virtually none or in a concentration ranging from 0.025 to 2.5 g/L; sodium and potassium in a concentration ranging from 0.025 to 2.5 g/L as sodium, whereby the potassium content is converted to sodium on a molar basis; zinc in a concentration ranging from 0.2 to 4 g/L; phosphate in a concentration ranging from 4 to 65 g/L and calculated as PO4; free fluoride in a concentration ranging from 0.03 to 0.5 g/L, and; total fluoride in a concentration ranging from 0.1 to 5 g/L. A zinc-containing phosphate layer is thereby deposited onto the metallic surfaces with a layer weight ranging from 0.5 to 10 g/m2.

摘要： The activating agent which is based on titanium(IV) phosphate and intended for use in the activation of metal surfaces before a zinc phosphating treatment contains one or more copper compounds and has a Ti:Cu weight ratio of 1:100 to 60:1 and optionally contains in addition at least one of the components consisting of condensed phosphate, silicate, complexing agent, water-soluble organic polymer, thickening agent, and surfactant. It is used to prepare aqueous activating baths for activating iron, steel, galvanized steel, zinc alloy-plated steel, aluminum-plated steel and aluminum before a zinc phosphating treatment, which baths contain 0.001 to 0.060 g/l Ti, 0.020 to 1.2 g/l orthophosphate (calculated as P.sub.2 O.sub.5), and 0.001 to 0.1 g/l Cu and so much alkali that the bath has a pH value of 7 to 11, preferably of 7.5 to 10.
