摘要： The invention relates to a corrosion protection method for application in connection with the production of finished metallic components from organically precoated metal sheets. In the course of such production, areas of uncoated metal which inevitably come about in the course of cutting, forming and joining the precoated metal sheets are provided with a chromium-free corrosion protection coat that is not a zinc phosphate coating, which serves at the same time as a tie coat for the subsequent finish. The treatment solution preferably contains fluoro complexes of Ti, Zr and/or Si and also organic polymers. The invention also embraces a metallic component treated accordingly.
摘要翻译：本发明涉及一种用于从有机预涂金属板生产成品金属成分的腐蚀保护方法。在这样的生产过程中，在切割，成形和接合预涂金属片的过程中不可避免地出现的未涂覆金属的区域设置有不含磷酸锌涂层的无铬防腐涂层，其在同一时间作为一个领带外套后续完成。处理溶液优选含有Ti，Zr和/或Si的氟络合物以及有机聚合物。本发明还包括相应处理的金属组分。
