摘要：

Corrosion by pits of a 303 steel was studied using a statistical method in NaCl 0.5 mol.1-1 solution in potentiostatic mode. Two populations of pits were observed. A population A on the visible inclusions and a population B off the visible inclusions. The distribution laws differ from one population to another. The population A obeys an exponential law with parameter lambda. The population B obeys a gaussian law. The surface density of the pits is an exponential function of the applied potential.
