Summary[edit]

Description
English: Principle of galvanic corrosion:
  • anode (less noble metal): dissolution of metal, reaction with water, acidification;
  • cathode (noblest metal): reaction of water and dissolved dioxygen, alcalinisation;
  • migration of ions due to the difference of electric potential, accumulation of anions around the anode.
Français : Princile de la corrosion galvanique :
  • anode (métal le moins noble) : dissolution du métal, réaction avec l'eau, acidification ;
  • cathode (métal le plus noble) : réaction de l'eau et du dioxygène dissout, alcalinisation;
  • migration des ions sous l'effet de la différence de potentiel électrique, accumulation d'anions autour de l'anode.
