Examination of Corrosion Sensor Data from Long-Term Field Exposures

To reduce maintenance costs while maintaining safety, different corrosion mitigation strategies have been utilized. In addition to new structural materials and advanced protective coatings, improved maintenance planning approaches, including Condition Based Maintenance (CBM) approaches, have seen growing use over the past decade. One goal of any Condition Based Maintenance (CBM) effort is to use all available on-aircraft data as well as field and depot-based maintenance information to align resources in a timely manner to ensure aircraft safety while reducing maintenance and repair costs.

To reduce maintenance costs while maintaining safety, different corrosion mitigation strategies have been utilized. In addition to new structural materials and advanced protective coatings, improved maintenance planning approaches, including Condition Based Maintenance (CBM) approaches, have seen growing use over the past decade. As a potential key component to CBM corrosion practices, corrosion sensors have received increased attention within the DoD. In this work, we discuss some generalized global findings based on a large scale sensor deployment at 10 different locations. In particular, comparisons between temperature, relative humidity, conductance, and corrosivity will be made.
