Deterministic analysis of processes at corroding metal surfaces and the study of electrochemical noise in these systems. Final technical report, 1 April 1989--31 March 1992

摘要

The control of metal dissolution processes is important in fields ranging from battery technology to corrosion. Nevertheless, metal dissolution remains a poorly understood class of electrochemical reactions. Although the reaction sequence for dissolution of many metals have been elucidated, kinetic descriptions are based on area averaged values of parameters that describe the relationship between the rate of reaction and the activation energy. Theoretical and experimental research on metal dissolution has focused traditionally on macroscopic processes and features. However, in the last few years there has been considerable interest in examining these processes on a microscopic scale. This proposal describes a research program to continue our work on theoretical modelling of metal dissolution. Over the next few years, results from theoretical modelling of dissolution, in conjunction with new experimental techniques such as in situ scanning tunneling microscopy, are expected to provide a new insight into the processes controlling metal dissolution and corrosion.
