Summary on Grant Application Form
The study of the re-formation of the surface of an oxide is of interest to the characterisation of corrosion. Previous investigations have employed mechanical exposure of a material to study the kinetics of corrosion under electrochemical control. inherent limitations with these techniques have been reported, associated with the often large and rapid current time transients recorded. These problems are the result of the relatively large surface areas exposed by the techniques employed. It is proposed here that inertial cavitation in close proximity to the surface on a microelectrode be employed to erode rapidly a small proportion of the surface of the electrode. This novel technique (as several key advantages. First, the exposure of the fresh surface is fast (ca. yes) compared to the electrochemical went. Second, both the areas eroded (100 hem 2) and the associated current are relatively small, enabling a reduction n ohmic distortion to be achieved. Third, many transients can be generated and analysed in a short period of time enabling validation of the results. These transients will be compared to a novel microelectrode fracture technique and :o transients obtained in the presence of corrosion inhibitors. The surfaces will be analysed ex-situ using conventional microscopy and SEM analysis.
