 What is Electrochemical noise and ECN analysis

Electrochemical Noise

 

 

During corrosion of two connected electrodes, fluctuations in corrosion potential and couplig current are often observed. Such fluctuations are called Electrochemical Noise and contains important information on the corrosion process.  For example, events involving rapid metal dissolution (anodic) or hydrogen discharge with gas bubble formation and detachment produce significant electrochemical noise.

 

The current and potential fluctuations are usually of relatively low amplitude, but can be easily measured with commercially available instruments.

 

Electrochemical noise analysis can be used to identify the type of corrosion (general or localised) and the corrosion rate without the application of any probing potential or current signal.
