| 摘要 |
The invention relates to an inexpensive and environmentally friendly method for electrochemically polishing steel, especially low-alloy steels. The method is characterized in that the workpieces, after electropolishing, are rinsed in a phosphoric acid/sulfuric acid bath containing little water in a first rinsing step, thereby preventing the freshly polished surfaces from chemical attacks without using inhibitors such as chromata which are environmentally harmful and injurious to health. Recirculation of the acids and rinse solutions allows to recover them, thereby creating a waste water-free process. |
