摘要： The invention relates to a multi-step method for the anti-corrosion pretreatment of components made from metallic material, in which following a wet-chemical treatment comprising an aqueous solution (A) containing a dissolved and/or dispersed polymer P, said polymer being substituted with heterocycles containing at least one quartenary nitrogen heteroatom, a conversion treatment based on aqueous compounds of the elements Zr, Ti and/or Si, is carried out, optionally prior to, additional coatings protecting against corrosion being applied.

摘要： The present invention relates to a method for serial surface treatment of metallic components comprising aluminium surfaces, wherein an alkaline pretreatment is followed by a conversion treatment. According to the invention, the intention during the alkaline pretreatment is that a maximum value for the concentration of dissolved zinc is not exceeded, in order to ensure a sufficient quality of the corrosion-protective coating on the aluminium surface of the components following the surface treatment. In a preferred embodiment, the content of dissolved zinc is effectively held below the respective bath-typical maximum value of dissolved zinc by the addition of compounds constituting a source of sulphide ions. The functionality of the surface treatment can be additionally increased by likewise controlling the content of dissolved aluminium in the alkaline pretreatment such that, by adding compounds constituting a source for silicate anions, a threshold value for dissolved aluminium is not exceeded.

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。
