Corrosion and anti-corrosives., Radio frequency identification systems.
A small, remotely accessed corrosion detector has yet to be realized despite corrosion being a major obstacle in maintaining metal structures. This work demonstrates a detector made using radio frequency identification (RFID) technology that is capable of fulfilling these requirements. A RFID tag was made using copper tape, a 100pF capacitor, and a 13.5 MHz microchip partially covered in a resistive polymer containing a corrosion susceptible material. This material was created using a thin section of copper tape. The functionality of the tag was monitored as the thin copper tape was corroded using ferric chloride. After the tag ceased working, it was visually determined that the thin copper tape had disintegrated. This indicated a positive result for the effect of corrosion on the tag. The tag is designed to corrode before the surrounding materials and can be sealed in a container as an early warning system for corrosion.
