Dear colleagues,
I read several papers about corrosion inhibition, but to be honest I'm unable to distinguish between a mixed type inhibitor and purely anodic or cathodic one. my question is how can I differentiate between types of corrosion inhibitors? and for example, if I had a mixed-type inhibitor how can I prove it from polarization curves and parameters such as Ecorr, ba and bcv? thank you in advance
Best regards

Dear Houda Serrar
to distinct between anodic, cathodic and mixte inhibitor, you must compared the anodic and cathodic densities in polarisation curves.
for exemple an purely anodic inhibitor decrease an anodic density and purely cathodic inhibitor decrease a cathodic density but the mixte inhibitor decrease the both anodic and cathodic densities.
but rarely when we found a purely anodic (or cathodic) inhibitor with one character (anodic or cathodic). so we found a mixte inhibitor with predominance anodic or cathodic.
Cordially
Dear brother,
Thanks a lot for explanation it helped me a lot, I hope that we will discuss more about this subject, thanks again.
Best regards,
Houda SERRAR
