摘要：

A tunable pulsed laser was used to promote local depassivation sites. This technique allowed us to simulate pulsed and focused depassivation. The first results concern the effect of the breakdown of the passive film on the pit initiation. These experiments are in progress in order to clarify the electrochemical steps determining the crack propagation during stress corrosion cracking.
