Galvanic corrosion occurs when two or more dissimilar metals are in contact or immersed in an electrolyte such as salt water. Basically a battery is created with the more active metal (the anode) corroding at a faster rate than the noble metal (the cathode). Stray electrical currents from poor grounds and bonding also lead to corrosion. A Silver-Silver-Chloride (Ag/AgCl) Corrosion Reference Electrode connected to a digital volt meter (such as our RDI-CRE-KIT Corrosion Detection Kit below) is used to measure the existing voltage potential. Corrections are then easily made to minimize corrosion by adding sacrificial anodes such as Zinc or correcting electrical problems. Galvanic Corrosion is of special importance to boat owners and the marine industry and will answer such questions as "are my zincs working?".
