Corrosion Monitoring

Corrosion monitoring is used to predict component wear out and to manage the corrosivity of the environment. There are a couple different methodologies used in the field of corrosion monitoring. One method uses probes (sensors) to monitor the chemical or electrochemical nature of the environment. The data collected is then used to relate to corrosion rates of materials, which is not always a direct method. Furthermore, probes can be adversely affected under certain conditions leading to erroneous corrosion rate determinations. A corrosion coupon is a second method, providing a low technology method to measure corrosion rates of materials. Acoustic emission is used to detect the formation of surface and subsurface damage in materials.
