| Abstract: |
| Once aluminum alloys are corroded, their electrical characteristics will be significantly changed. Based on this principle, the corrosion sensors have been developed by detecting the changes in electrical characteristics to evaluate the corrosive degree for aluminum alloy structure. Currently, a series of corrosion sensors have been developed, which can capture the corrosive effect of aluminum alloy structures, including galvanic corrosion sensor, resistance corrosion sensor and impedance corrosion sensor and so on. The development and application of these corrosion sensors provide technical backup and effective means for the early detection of corrosions in the aircraft structure, and help to adopt corrosion resistant maintenance or protection measures in a timely manner so as to reduce or avoid severe corrosion failures of the aircraft structure. Finally, the working principles and application situations of the corrosion sensors were summarized, and the future development trend for the corrosion sensor technology was pointed out. |
