Chrome(VI)free Layer systems

In order to directly modify the characteristics of the surface, still further subsequent treatment steps can take place after zinc or zinc alloy and Chromiting/Blackchromiting.

Possible targets of the subsequent treatment are the color change (decolorize, indication), the friction value adjustment,
the increase of the corrosion protection as well as stabilization.

Optimal corrosion protection


what can be obtained through suitably combined layer systems?

Stabilization
