摘要：

The nucleation of corrosion pits on stainless steel in chloride environments is described in terms of minute transient currents recorded under high resolution. Nucleation is fast, showing a rise time less than 1 ms, and is ascribed to rupture of the passivating oxide film, caused by the formation of microscopic patches of metal chloride at the metal-oxide film interface. The embryonic stage of pit propagation is reported.
