| Abstract: | Mechanism and influential factors are analyzed for the silver surface tarnishing on exposure to atmosphere containing S-compounds.The methods and the precesses of the silver anti-tarnishing,such as extremely thin metal coating,anodic passivation treatment,cathodic electrophoresis,chemical passivation and self-assembled monolayer (SAM),have been evaluated.The packaging materials having protective properties would provide an easy way for preventing tarnishing of silver. |
