Ruthenium - Elektrolyteedelmetallbaeder_ruthenium

Ruthenium is characterised by having a good abrasion resistance and hardness. Ruthenium electrolytes from METAKEM are used for technical and decorative applications. Dark, anthracite-black coatings are deposited. The coating colours can be influenced by addition of blackening additives. Ruthenium electroplating baths are used in particular for the selective deposition on for example gold - to achieve high-contrast surfaces in terms of colour.
