Mercedes – DBL 8451

This specification covers the Corporation’s requirements for electrodeposited zinc coatings. Provision is also made to specify mechanical plated coatings by the addition of a suffix to the class designation. Zinc plating is used primarily for corrosion resistance. Parts to be plated will be thoroughly cleaned and free of rust, scale, oil and other foreign matter. The cleaning operation must be controlled to prevent hydrogen embrittlement, especially in those parts that are hardened, cold worked or subject to high service stresses.
