Artificial pitting corrosions on the surface of a stainless steel plate were measured with a photothermal electrochemical (PE) detection scheme. The principle of PE detection is based on the accelaration of chemical etching by the use of laser irradiation. As specimens, artificial pitting corrosions were made by potentiostatic electrochemical method. The periodically modulated beam of an Ar^+ -ion laser is focused on the surface of a stainless steel plate, which is immersed in a 3.5% sodium chloride (NaCl) aqueous solution. Nondestructive measurement of artificial pitting corrosions were carried out using a photothermal electrochemical (PE) detection scheme. The PE images and signals varied with the shape of artificial pitting corrosion.
