Electric zinc galvanizing with trivalent chromate conversion (blue/white or yellow converter).  Trivalent chromate conversion with yellow converter is one of a variety of chromate conversion coatings available for use on Eberhard parts.  Chromate conversion coatings are produced on various metals through chemical or electrochemical treatment with mixtures of trivalent chromate conversion and certain other compounds.  Through these treatments, the metal surface is converted to a superficial layer containing a complex mixture of trivalent chromate conversion compounds. Thickness from 12~20micro
