Corrosion of structures and mobile equipment is a concern for all nations as it affects through-life costs, safety, and availability. Historically, corrosion monitoring has relied on visual inspections which hinder its detection in inaccessible areas, and by the time the corrosion damage is caught, requires potentially extensive and expensive repairs. The development of a low-cost and simple to operate corrosion monitoring system that would both aid in early detection and provide cumulative damage information would greatly improve the maintenance efforts. Most currently available corrosion monitoring systems require either powered sensors or a physical connection to the sensors to obtain measurements, which makes the sensor design and the measurement complicated and expensive. In this study, a cost-effective wireless corrosion monitoring system based on radio frequency identification technology (RFID) was developed. A sacrificial metallic coating was applied to the surface of RFID tags to partially block the communication between the tag and the reader. As the coating corroded, the signal was restored. By establishing a correlation between the corrosion rate of the metal object and the sensor communication performance, it will be possible to wirelessly monitor the cumulative corrosion damage.
