Passivations / Chromating

Chromating (based on hexavalent chromium), passivation (based on trivalent chromium) and sealants (organic, inorganic and hybrid) protect zinc and zinc alloy coatings and thus optimise the corrosion resistance of the coating systems. In addition, lubricants can be used to define the coefficient of friction of the surface.

Passivations and chromating are used for

cathodic corrosion protection (CRC)
