|Type of plating||Features||Characteristic value|
|Palladium (Pd) plating||- Palladium is used as catalytically active (noble metal catalyst) plating indispensable for plating of ceramics and plastics.
- With its catalyst activity being too strong, airborne organic substances become polymers, causing contamination of contacts.
- Application as a hydrogen gas purification film
Impurity gasses in hydrogen gas are removed by using the hydrogen permeability of palladium plating. (Role as a hydrogen gas filtration membrane)
