Abstract A systematic investigation was made on the change of potential at pit bottom on aluminium alloy 3003 in neutral chloride solution (3.5%NaCl) with potentiodynamic, galvanodynamic, potentiostatic and galvanostatic measurements. The potential at pit bottom of this metal in the solution is more positive than that on surface. The larger the dissolution current, the more positive the potential at pit bottom is than that on surface. The pit bottom potential is gradually getting negative at constant current.
