摘要： The invention relates to a wet-chemical pretreatment of zinc surfaces prior to applying a corrosion-protection coating, which deposits a thin inorganic coating of oxide and/or metallic iron. An iron layer structure which is applied according to the invention, hereinafter referred to as ferrization, improves the achievable corrosion protection of wet-chemical conversion coatings on zinc surfaces. Furthermore, the ferrization process causes both a reduction of the contact corrosion of joined metal components which have zinc and iron surfaces as well as a reduction of corrosive coating migration on cut edges of galvanized steel strips with coating layer structures. In particular, the invention relates to an alkaline composition containing an iron ion source, a reducing agent based on oxoacids of nitrogen and phosphorus, and water-soluble organic carboxylic acids with an amino group at the α, β, or γ position with respect to the acid group and/or the water-soluble salts thereof.
摘要翻译：本发明涉及在施加防腐涂层之前锌表面的湿化学预处理，其沉积氧化物和/或金属铁的薄无机涂层。根据本发明应用的铁层结构（以下称为铁质化）改善了锌表面上湿化学转化涂层的可实现的腐蚀保护。此外，铁化过程同时导致具有锌和铁表面的接合金属部件的接触腐蚀的降低以及在具有涂层结构的镀锌钢带的切割边缘上的腐蚀性涂层迁移减少。特别地，本发明涉及含有铁离子源，基于氮和磷的含氮的还原剂和在α，bgr或γ位置具有氨基的水溶性有机羧酸的碱性组合物，相对于酸组和/或其水溶性盐。

摘要： The invention relates to a method for the anti-corrosive pretreatment of tinplate, in which an anti-corrosive primer coating is applied in a single step, said primer coating effectively preventing the shiny metal surface of the pretreated tinplate from turning black when the pretreated tinplate of the invention that is provided with a topcoat is in contact with liquids releasing or containing sulfur compounds and with food containing protein. In the disclosed method, the tinplate is anodically polarized in an electrolyte containing silicates of formula M2O.nSiO2, where M is an alkali metal ion or quaternary ammonium ion and n is a natural number between 0.8 and 7. Tinplate pretreated according to the invention can be used in particular for the production of food-safe packaging such as beverage cans or tin cans.
摘要翻译：本发明涉及一种用于马口铁的防腐蚀预处理方法，其中单次施加抗腐蚀底漆涂层，所述底漆涂层有效地防止了预处理马口铁的光泽金属表面变黑，当预处理马口铁提供有面漆的本发明与释放或含有硫化合物的液体和含有蛋白质的食物接触。在所公开的方法中，马赛克在包含式M 2 O·nSiO 2的硅酸盐的电解液中进行阳极极化，其中M是碱金属离子或季铵离子，n是0.8-7之间的天然数。根据本发明预处理的锡板可以特别用于生产食品安全包装如饮料罐或锡罐。
