| Abstract: |
| The silver craftwork's anti-sulphur corrosion is studied after treated by chromate passivation process and organic passivation process, the ammonium sulphide solution is used as sulphur medium. The results show that the potassium bichromate plus nitric acid or glacial acetic acid has the best anti-corrosion effect. |
