CAUTION: If you select corrosion coupons that are of different metal compositions and you intend to use them together, be sure that they are ordered properly in the corrosion coupon rack with regard to flow. The most anodic metals should always be up stream of the cathodic metals. The flow order for our coupons should be: Zinc, Galvanized Steel, Aluminum, Mild Steel, Lead, Admiralty Brass, Copper, Stainless Steel(304), and Stainless Steel(316) The difference between the Zinc and Galvanized Steel coupon is somewhat arbitrary since Galvanized Steel is merely Zinc coated steel. Only if there are pits formed in the Galvanize coating that actually reach the steel, would the Zinc Coupon would become anodic with respect to the Galvanized Steel coupon. As a matter of practice, we never use the Galvanized Steel Coupons, but use the Zinc ones instead.
