Cr (Chrome)

Brief technical description:

• Chrome is also used in various Cu/Ni coating systems as a decorative and corrosion protective coating. Electrolytically precipitated chrome coatings are glossy silver in colour and have a hardness of 750-1200 HV. As all oxidation agents act as chromium passivators, a thin oxide layer is formed on all chrome coatings when they come into contact with oxygen in the air. This in turn gives the chrome layer a precious metal appearance. A large variety of base materials, steel, stainless steel, brass, bronze, aluminium, sintered metals and die-cast metals can be coated. Special emulsions can be added to provide the light chrome surfaces with a deep-black, silky finish.

Advantages:

• high wear resistance
• low friction values
• high surface tension
• very resistant against chemical attack by gases, acids, alkalines and saline solutions.

Please note:

• Chrome surfaces have poor wetting properties, e.g. with regard to oils, paints and varnishes. This also means that they are not easily soldered.

Fields of application:

• Automotive (corrosion and wear protection for interiors and exteriors)
• on aluminium profiles and bathroom fittings
• Mining and mechanical engineering (hydraulic parts, etc.)
• Chemical industry (protection against aggressive media)
• Consumer industry (decoratively glossy, corrosion-resistant surfaces)
• Paper, packaging and textile industry (wear protection on roller surfaces)
