Using the Butler-Volmer equation for small η, i.e. ,for potentials close to corrosion potential, the Butler-Volmer equation can be reduced to: Alternately, if the expression is rearranged: The ...

Engine corrosion is accelerated by excessive acidity in alcohol-based fuels. Total Acid Number, otherwise known as TAN, accounts for all titratable acids no matter their strength and therefore is ...
