In the present study we have developed a miniature high pressure cell (with similar performance to a normal autoclave) where the tests are performed in-situ under a gaseous environment (up to 1000 psi in a mixture of a gas and liquid environments up to 200oC). The surface of the sample inside the chamber has been video recorded while the electrochemical measurements on the surface of the sample are done. The main objective of these measurements is to confirm (visually) and electrochemically the conditions under which the transition from passivity to corrosion may take place. This methodology allowed the real-time in-situ anodic polarization while determining the sites for pit initiation in Duplex Stainless Steels in chloride containing environments.
