Smart Sensing of Corrosion with Fiber Optics

5 Smart Sensing of Corrosion with Fiber Optics 

The techniques described so far have all progressed to industrial apph-cations. A number of less well-known techniques are currently emerging from research and development efforts. There can be httle doubt that several of these will find increasing commercial apphcation. Some 

The HAZ is anodic to the weld metal and the parent plate. The weld metal is cathodic to the parent plate. 

The weld metal is slightly cathodic to the parent plate. 

There is a trend toward utilizing the versatility of fiber optic sensors to monitor atmospheric corrosivity and the effects of corrosion on a structure. Emerging techniques for monitoring air corrosivity include
