Burnishing method and composition |
| abstract |
A burnishing liquid used in a physicochemical mass finishing process serves to chemically remove the conversion coating as well as to promote brightness of the treated metal surface. The burnishing liquid has a very low content of organic constituent and therefore a low chemical oxygen demand characteristic. The burnishing liquid comprises a water-soluble tetrapyrophosphate or hexametaphosphate and has a pH of about 8.5 to 10.5. |
