1. A system for measuring corrosion, comprising:
a first electrode configured to be connected to a first structure; and
a second electrode configured to be connected to a second structure, wherein the first and second structures are galvanically-coupled together, wherein the first and second structures are made of different materials, and wherein the second structure comprises plastic;
a cyclic corrosion chamber configured to run through one or more testing cycles while the first electrode, the first structure, the second electrode, and the second structure are positioned inside the chamber, wherein the one or more testing cycles comprise a wet cycle and a dry cycle, wherein the first and second structures are configured to be sprayed with a liquid solution during the wet cycle, and wherein the first and second structures are configured to be blown with air during the dry cycle; and
a measurement device configured to receive data from the first and second electrodes and to measure one or more parameters based at least partially upon the data, wherein a level of corrosion on the first structure, the second structure, or both is configured to be determined based at least partially upon the one or more parameters.
