The objective of this research project was to investigate the initiation and formation of localized corrosion pits on stainless steel samples. By using a scanning electrochemical microscope (SECM), the effects of varying Cl{sup -} concentration, pH, and sample potential on these processes were studied. Initiation and growth of single pits were attained by using the SECM tip to electrogenerate Cl{sup -} in an extremely small area on a metal sample, thus forming localized pits. Imaging of the sample surface was achieved via detection of surface conductivity by the SECM.
