MERCEDES-BENZ – DBL 8451
Electrodeposited Zinc or Zinc Alloy Coatings
This DBL describes the special requirements, properties and planning data for parts with electrodeposited zinc and zinc alloy coatings and subsequent post treatment. Although the End-of-Life Vehicle Act does not currently apply to heavy-duty trucks or buses, for reasons of variant reduction in new designs, consideration should be given to also specifying Cr(VI)-free
surfaces for commercial vehicle parts. The function properties shall be checked when changing to Cr(VI)-free surfaces. For notes on corrosion resistance and recommendations for various application cases, see Tables 2 to 4.
