ZINC Plating SPECIFICATION – Mercedes-Benz – DBL 8451

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.
