What Does Repassivation Potential Mean?
Repassivation potential refers to an electrochemical property of a metal that describes the degree of decreasing current from increasing current in a highly negative electrode. This quantification is used to determine the compatibility between substrate metals and metals that are used to coat the substrate with the intention of preventing corrosion.
Passivation involves applying an outer layer to a metal to protect it from harmful reactions such as corrosion. Repassivation is repeating the process after a period of time due to the protective coating wearing down.
