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 5 on the surface of silver by depositing successive molecule layers of the coating material. For example aluminum oxide (Al 2O3) or zirconium oxide may be used as the coating material.
