... place at electrodes of different iron sulfide polymorphs (namely troilite, pyrrhotite and pyrite) in sour aqueous solutions have been studied using electrochemical techniques. Also, the effect of galvanic coupling between different iron sulfides and steel electrodes has been investigated. The results...

... that it was a good vapor corrosion inhibitor for steel. It suppressed the cathodic reaction of steel electrode and depressed passive region current density of anodic process. Fourier transform infrared (FTIR) was used to characterize the adsorption of MPO on steel surface. The different polar groups of MPO had...

... utilities with probes containing copper electrodes, steel electrodes, or lead electrodes. The loops were operated for times varying from five weeks to four months. At some locations, the effectiveness of either zinc orthophosphate or blended orthophosphate corrosion inhibitor was tested. After testing...

... ABSTRACT The first part of the work describes experiments performed with a NAD-dependent hydrogenase and a 316L stainless steel electrode in thin spectroelectrochemical cells (TSEC). Constant potential electrolyses were carried out at different potential values. Current and absorbance through...
