Post-passivation method for phosphated metal surfaces |
| abstract |
(57) [Summary]nPhosphated metal surface, characterized in that the phosphated metal surface is treated with a post-passivating aqueous solution containing 50 to 500 mg / L of nickel ions and 200 to 1500 mg / L of phosphate ions. After passivation method. The resulting wash water containing the components of the post-passivating solution can be treated by nanofiltration or reverse osmosis and the Ni circuit closed by transferring the retentate into the phosphating bath. it can. The post-passivation solution preferably further contains a phosphating accelerator. |
