Abstract:
1. An electrochemical probe for corrosion monitoring in a non-aqueous system that forms electron-conducting deposits on the probe, comprising: (a) a plurality of electrodes; (b) a body wherein a portion of each electrode is embedded to form a probe and the remaining portion of the electrodes is exposed out of the probe body; (c) electrical leads connected individually to each electrode at the end of the electrodes that are being embedded; (d) an electrical insulating coating; and (e) an ion conducting coating applied on the outside surface of the electrically insulating coating; wherein the insulating coating is applied on each of the electrodes, such that all surface area of the exposed electrode—except for the electrode tip that serves as the sensing area of the electrode—is covered by the insulating coating and the electrodes are spaced such that there are gaps between the outside surfaces of the outer coatings of the adjacent electrodes near the sensing areas to prevent the formation of continuously distributed electron conducting deposits on the electrodes that may cause short-circuiting between the sensing areas of any two electrodes, while the ion conducting coating ensures the ion conducting path between the sensing areas of any two electrodes.
