New Experimental Techniques for In-situ, Real-time Corrosion Monitoring

Abstract

Abstract ABSTRACT Experimental techniques for qualitative and quantitative analysis of corrosion have been discussed. The application of spectroscopic (optical and electrochemical) methods has been highlighted. Capabilities of Raman spectroscopy have been illustrated with suitable examples of CO2 detection in water and gas corrosive environments, as well as, for monitoring corrosion products (in situ and real time). The application of nanomaterials in corrosion monitoring technologies is also discussed, within the context of utilization of Raman spectra for species detection. The concept of “nano-coupons” is designed to provide faster, measurable corrosion responses and is expected to support more accurate corrosion rate measurements on a real time basis.
