SELGA-COAT® CHROME: Selective Galvanic Plating of Functional Hard Chrome Layers

In nearly all areas of the automotive industry and mechanical engineering, technical hard chrome layers are applied to impart components with a property profile for their intended use: hardness, corrosion resistance, wear resistance, tribological properties, as well as thermal and chemical resistance. The very good tribological behaviour of functional hard chrome layers is indicated by its relatively high original hardness, strong adhesive, constantly renewing oxide layer and anti-adhesive properties. In addition, the metal features a hexagonal lattice micro-structure when plated. Therefore, the wear-intensive frictional surfaces are absent in the micro-structure.
