Coatings (such as electroplates)

In Djinn it is considered that a coating entirely covers the substrate, so we assume that with respect to the measured polarization data of the coating, it does not matter what the substrate is, as it will not be adjacent to the electrolyte. With this in mind, in order to choose a coating, we simply have to select a Type of Coating.

Figure 1 shows the choices to analyze the galvanic couple between Stainless Steel 15-5 PH and a Zinc-Nickel LHE coating.

Figure 2 shows the results of the analysis between the stainless steel and the Zinc-Nickel LHE coating. The Zinc-Nickel is clearly more active, as would be expected of Zinc-Nickel coatings, which are often used for sacrificial protection.
