Electrolessly Coated Optical Fibers for Distributed Corrosion Monitoring

Available for download

To develop a distributed optical sensor for corrosion monitoring metallic thin films were deposited onto optical fibers through electroless plating. The conditions and procedure for electroless deposition were developed to obtain the optimal metallic coatings on optical fibers. The coated optical fibers were tested in CO2-saturated 3.5%wt. NaCl solutions at 30 oC. The optical transmission through the coated optical fiber was measured and served as a parameter for corrosion detection and quantification in the tested environment. Surface analyses using scanning electron microscopy and X-ray photoelectron spectroscopy were performed on the metallic thin films. The distributed corrosion monitoring was realized using an optical backscattered reflectometer system which provides the spatial profile of corrosion along the fiber.
