The Application of scanning electrochemical microscope in the st udy of corrosion of metals

Since the inception of the Scanning Electrochemical Microscope (SECM), it has been used to inves tigate the local corrosion of high spatial and temporal resolution sys tems. SECM is a unique scanning technique used electrochemically for the detection of chemicals and electrochemical activities in heterogeneous electrochemical sys tems such as corrosion inves tigations. It is also used to s tudy the initiation and propagation of cavities, surface micros tructures, electron transfer kinetics as well as the effectiveness of various protection schemes including coatings, inhibitors and enhancers.
