RE: chromate passivated zinc coating
As for the rest, it is a zinc coating deposited either electrolytically or mechanically which is then treated with a chromate ion containing solution that results in an outer conversion layer. This layer contains hexavalent and trivalent chromium ions which improve corrosion resistance of the coating.
