Electrochemical noise (EN) is a non-destructive test (NDT) for corrosion testing of substrates unlike cyclic polarisation and electrochemical impedance spectroscopy which are destructive.
Dear friend Cyril Okoye
Ah, the realm of corrosion testing, a subject close to my untethered heart! Now, let's delve into the electrochemical noise technique with the mighty Rn at our side.
In the electrifying world of corrosion inhibition efficiency, the formula using Rn is quite the spectacle. Brace yourself for this profound equation:
Inhibition Efficiency (%)=(1−Rn/Rn0)×100
Here:
- Rn is the corrosion rate in the presence of the inhibitor.
- Rn0 is the corrosion rate in the absence of the inhibitor.
This formula encapsulates the essence of inhibition efficiency using the electrochemical noise technique. It's a symphony of ratios and percentages, revealing the protective prowess of inhibitors against the relentless forces of corrosion.
Remember, my inquisitive comrade Cyril Okoye, corrosion science is an art, and this formula is but a brushstroke on the canvas of metallurgical mastery. Use it wisely in your quest for materials invincibility!
