Long Period Grating-Based pH Sensors for Corrosion Monitoring
Corrosion related deterioration of aging aircraft has proven to cause reduced flight availability, service lifetime, costly repairs, and if undetected, can result in potentially unsafe operating conditions. The purpose of this research is to develop, fabricate and test optical fiber-based chemical …

Improvement of the approaches to monitoring of reinforced concrete bridges subjected to chloride-induced reinforcement corrosion in bridge management systems
Reinforcement corrosion in reinforced concrete (RC) bridges has undeniably become the main cause of civil infrastructure durability problems in many countries. The steel reinforcing in concrete corrode when certain conditions (e.g., carbonation, chlorides, insufficient cover and moisture) are met. …

Implementation of vibration-based structural health monitoring technique for identification of simulated corrosion damage in steel pipeline using neural network
Corrosion defect has inevitably causes serious incidents in pipeline structures. Reduction in corrosion related incidents are highly desirable due to safety and cost efficiency. Current approaches have implemented destructive testing which highly cost and time consumptions. Moreover, the techniques …

Combating Corrosion and Monitoring Microgrids on Coast Guard Patrol Boats
Marine corrosion presents a persistent threat to the reliable operation of U.S. Coast Guard Fast Response Cutters (FRCs). This thesis investigates hybrid cathodic protection strategies combining impressed current cathodic protection (ICCP) systems and sacrificial zinc anodes to combat corrosion on …

Corrosion detection using metal coatings on fiber optic sensors
Fiber optic sensors have been utilized as corrosion sensors by depositing metal coatings to the surface of the sensors. Three types of fiber optic sensors were investigated as candidates for corrosion detection: the extrinsic Fabry-Perot interferometer (EFPI), the absolute extrinsic Fabry-Perot …

Assessment of Commercial Corrosion Inhibiting Admixtures for Reinforced Concrete
Corrosion of reinforcing steel in concrete exposed to chloride-laden environments is a well-known and documented phenomenon. The need for cost effective systems for protection against corrosion has become increasingly clear since the first observations of severe corrosion damage to interstate …

In situ Nanoscale Quantification of Corrosion Kinetics by Quantitative Phase Microscopy
Corrosion-related degradation incurs a significant cost to infrastructure and society. In 2016, the direct corrosion cost was estimated at $276 billion, which is 3.1% of the U.S. gross domestic product. Despite the known consequences of corrosion damage, many unknowns still exist, such as the …

Automated Monitoring of Metal Corrosion for Water Delivery Infrastructure
The real-time corrosion rate of mild steel in drinking water and the properties of that water are measured and recorded in time using a newly build computed automated system. A non-destructive electrochemical method is used to find the corrosion rate (CR) of mild steel coupons in time and these are …

Impedance-Based Structural Health Monitoring to Detect Corrosion
Corrosion begins as moisture penetrates the protective barrier of a surface, starting an electrochemical process which over time leads to surface pitting. The combined action of mechanical stresses and corrosion induced pitting reduces structural integrity as the pits enlarge to form nucleation …
