Abstract
This chapter presents the forms of energy dissipation involved in a corrosion process when a positive driving voltage is available for corrosion to take place, as defined by thermodynamics, and how they concur to determine the overall corrosion rate . Dissipations are described in terms of overvoltage of the different processes involved, which are classified as activation overvoltage (metal corrosion , hydrogen evolution), represented by Tafel law , concentration overvoltage (oxygen diffusion ) and ohmic drop (electrolyte resistivity ). The trend of the overvoltage for an active -passive metal is also described in the different potential ranges, corresponding to immunity , activity, passivity and transpassivity (or localised corrosion ).
No more can we observe what’s lost at any time,
When things wax old with eld and foul decay,
Or when salt seas eat under beetling crags.
Lucrezio, De Rerum Natura, Book I, 319–327

Notes
- 1.
Roberto Piontelli (1909–1971) was an eminent Italian electrochemist.
- 2.
John Alfred Valentine Butler (1899–1977) was an English physical chemist who developed kinetic theories of the origin of electrode potentials and developed the general theory of overvoltage with hydrogen and oxygen electrodes. Max Volmer (1885–1965) was a German physical chemist, who made important contributions to electrochemistry, in particular on electrode kinetics. He co-developed the Butler–Volmer equation.
- 3.
Julius Tafel (1862–1918) was a German chemist who worked in electrochemistry with Wilhelm Ostwald.
- 4.
The letter is part of Volta’s correspondence with the Dutch physics Van Marum, who has a powerful scrubbing electric machine in Rotterdam. Unfortunately, Van Marum, unlike what he did with previous letters, does not make it public. The letter was only disclosed in 1905 when J. Bosscha published the correspondence Volta-Van Marum.
