Depassivation Experiments by Laser‐Pulse‐Induced Spallation

Depassivation experiments have been conducted by applying a technique developed for adhesion tests. A laser-pulse-induced spallation of the passive film is induced in situ without any contact between the laser beam and the passive film. The depassivation is controlled by the short pressures induced at the metal-film interface. The interfacial stresses at the metal-film interface could be studied by this technique
