摘要： Vorliegende Erfindung betrifft ein Verfahren zur schichtbildenden Zinkphosphatierung von Bauteilen umfassend Oberflächen von Stahl mit hoher Toleranz gegenüber im Zinkphosphatierbad gelöstem Aluminium, bei dem die Ausfällung schwerlöslicher Aluminiumsalze weitgehend vermieden werden kann. In dem Verfahren wird auf eine Aktivierung der Zinkoberflächen mittels Dispersionen enthaltend partikuläres Hopeit, Phosphophyllit, Scholzit und/oder Hureaulith zurückgegriffen, wobei der Anteil an partikulären Phosphaten in der Aktivierung der Menge an freiem Fluorid und gelöstem Aluminium in der Zinkphosphatierung angepasst werden muss.

摘要： The invention relates to a multistage method for treating composite metal constructions for corrosion protection, comprising metal surfaces of aluminum, zinc, and optionally iron, wherein, in the first step, the selective zinc phosphating of the zinc and iron surfaces is carried out using a phosphating solution, comprising water-soluble inorganic compounds of silicon in a quantity sufficient for suppressing pinholing on the zinc surfaces, but not exceeding a quantity at which the zinc phosphating loses selectivity. In the subsequent second step of the method according to the invention, the aluminum surfaces are passivated by means of an acid treatment solution. The invention further relates to a zinc phosphating solution suitable for use in the method according to the invention comprising 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, wherein the product (Si/mM)-(F/mM) of the concentration of silicon (Si in mM) in the form of water-soluble inorganic compounds and the concentration of free fluoride (F in mM) divided by the number of points of free acids is no greater than 5.

摘要： The present invention relates to a chromium-free aqueous agent based on water-soluble compounds of titanium and/or zirconium and a source of fluoride ions, copper ions and metal ions selected from the group consisting of calcium, magnesium, aluminum, boron, zinc, iron, manganese and/or tungstene and to a method for the anti-corrosive conversion treatment of metal surfaces. The chromium-free aqueous agent is suitable for the treatment of various metal materials, joined in composite structures, amongst others of steel or galvanized steel or the alloys thereof or any combinations of said materials. Furthermore, surfaces of aluminum and alloys thereof can be treated in an anti-corrosive manner using the agent according to the invention. The anti-corrosive treatment is intended in particular as a pretreatment for a subsequent dip-coating. The invention further relates to a metallic substrate that was treated according to a predefined method sequence with the chromium-free agent according to the invention and to the use thereof, particularly in the automotive production of vehicle bodies.

摘要： An acid, aqueous phosphatising solution containing 0.2 to 3 g/l zinc(II) ions, 3 to 50 g/l phosphate ions, calculated as PO43-, 15 to 50 mg/l hydrogen peroxide or an equivalent amount of a hydrogen peroxide-cleaving substance, 0.5 to 1.5 g/l one or more aliphatic hydroxycarboxylic acids with 3-6 C atoms, has a free acid content of maximum one point; in a process for phosphatising metal surfaces made of steel, zinc-coated steel or alloyed zinc-coated steel and/or aluminium, the metal surfaces are brought into contact with this phosphatising solution by spraying or dipping, or by a combination of the same, for a period of 3 seconds to 8 minutes.

摘要： The present invention relates to an anti-corrosion treatment method where a series of components having metallic surfaces of iron and/or zinc are contacted with a passivating aqueous pretreatment solution which is located in a system tank and contains compounds of the elements zirconium and/or titanium and also a source of fluoride ions. In the method of the invention a portion of this pretreatment solution is discarded and replaced by an in total at least equal volume portion of one or more such supplemental solutions, which are metered into the pretreatment system tank. While the discard must not exceed a predetermined level, depending on the molar ratio of the elements fluorine to zirconium and/or titanium, in order to ensure a permanently satisfactory anti-corrosion treatment even when not using any chemicals at all to regulate the pickling rate or stabilize the ionic load, the way in which supplemental solution is metered in ensures maintenance of the concentration of the elements zirconium and/or titanium in the passivating aqueous pretreatment solution in the form of water-soluble compounds.
摘要翻译：本发明涉及一种防腐蚀处理方法，其中具有铁和/或锌的金属表面的一系列组分与位于系统罐中且含有元素锆化合物的钝化水性预处理溶液和/或钛以及氟离子的来源。在本发明的方法中，将该预处理溶液的一部分丢弃并用总计至少等体积的一种或多种这样的补充溶液代替，其被计量加入预处理系统罐中。虽然废弃物不能超过预定的水平，但是根据元素氟与锆和/或钛的摩尔比，为了确保永久令人满意的防腐处理，即使完全不使用任何化学物质来调节酸洗率或稳定离子载荷，计量补充溶液的方式确保钝化水性预处理溶液中元素锆和/或钛的浓度以水溶性化合物的形式维持。
