PROTECTIVE COATING OF SILVER |
| 摘要 |
In the method, silver is protected against tarnishing using an Atomic Layer Deposition method. In the Atomic Layer Deposition method, a thin film coating is formed on the surface of silver by depositing successive molecule layers of the coating material. For example aluminium oxide (Al2O3) or zirconium oxide may be used as the coating material. |

1. A method for protecting silver products, articles or parts against tarnish in an atmosphere, the method consisting of applying a thin coating layer of protective material having a thickness between 2 nm to 20 nm on at least a part of an outer surface of a silver product, article or part using an ald (atomic layer deposition) method to prevent tarnishing of the outer surface of the silver product, article or part in the atmosphere. |
