5/13/2023 0 Comments Limitations by JD Riggs![]() It is not so well known that corrosion can also be prevented in suitable cases by anodic polarisation, and it is certainly very much more difficult to understand why this should be so from the somewhat oversimplified theory of corrosion which the non-specialist is bound to have. ![]() In fact, the position is somewhat more complicated and, in many cases, other factors override this apparently simple one. Corrosion involves the oxidation of the metal and it is reasonable to expect that cathodic polarisation, which discourages oxidation and favours reductions at the metal surface, should tend to cause protection. It is well known that corrosion can sometimes be controlled by cathodic currents and, even with an elementary knowledge of electrochemistry, it is easy to appreciate why this should be so.
