Many new surface finishes have been proposed for zinc die casting. In many cases these are intended to replace the traditional processes of solvent-based painting, electroplating and hexavalent chromium. Twenty new coatings were offered by suppliers and were subjected to cyclic corrosion testing (CCT). A wide variation in results was seen, suggesting the need for further development in come cases. However, several of the new environmentally friendly finishes are of interest for current application.
