Microelectrodes for Corrosion Studies^★ Available to Purchase

Microelectrode technology is currently being developed by medical and biological workers for use in microanalytic and intracellular studies. The possibilities of applying this new technology to investigations of corrosion phenomena are examined in the paper. Oxygen cathode, pH and potential-measuring microelectrodes with working tips ranging from 10 to 100 microns in diameter are being developed for the study of corrosion mechanisms. Techniques for the construction, storage, calibration and use of stable electrodes are described. Probe dimensions and very high impedance characteristics lead to positioning and electrical measurement difficulties which are also discussed.
