| titleOfInvention | Pretreating zinc surfaces prior to a passivating process |
| abstract | The present invention relates to a wet chemical pretreatment of the zinc surface before application of the anticorrosive coating. Wet chemical pretreatment results in the deposition of a thin inorganic coating consisting essentially of iron oxide and / or metallic iron. The iron coating layer (hereinafter referred to as ferrite) applied according to the present invention improves the achievable anticorrosive properties of wet chemical conversion coatings known from the prior art on zinc surfaces. In addition, the ferrite process reduces contact corrosion of bonded metal parts with zinc and iron surfaces and reduces corrosive coating infiltration at the cutting edges of galvanized steel strips with a coating layer structure. In particular, the present invention relates to an alkali composition for ferrite purposes, said composition comprising a source of iron ions, a reducing agent based on elemental nitrogen and phosphorus oxo acids, a water-soluble organic carbo having an amino group at the α, β or γ position relative to the acid group. Carboxylic acids and / or water-soluble salts thereof. |
