Non-Uniform Copper Corrosion in Potable Water: Theory and Practice
… on measurement of electrochemical potential (Ecorr) in waters of this type as a function of sulfide concentration, that the onset of pitting would be associated with decreasing Ecorr with time. If so, the fundamental basis of tracking Ecorr rise with time to predict pitting propensity would be …

Development of new coating alloys
… current density (Icorr), corrosion potential (Ecorr), types of electrolytes, and their concentrations extracted from the literature and computed TL for each alloy, to train machine learning (ML) models. ML tools including the Citrination platform® and various open-source Python libraries were …

The detection of crevice corrosion in titanium and its alloys through the use of potential monitoring
… relationship between the corrosion potential (Ecorr) and crevice corrosion initiation and propagation was readily determined. Corresponding crevice corrosion initiation and steady state propagation surface morphology was also examined.

Synthesis, Characterization and Corrosion Inhibition Investigation of substituted triazines on aluminium and mild steel in 1M HCl: Experimental and Theoretical approach
… surface. The PDP results revealed an increase in Ecorr (a less negative value) was observed with a sustained rise in the DMT, DPT, and DNT concentration. For Al, all inhibitors are either anodic or cathodic inhibitors according to changes in Ecorr and mild steel PDP, revealed that all the …

Corrosion behaviour of welded joints within chloride and chloride/CO[2] environments.
… resistance (LPR), corrosion potential (Ecorr)} zero resistance ammetry (ZRA), cathodic polarisation (CP) and the scanning vibrating electrode technique (SVET), which were used to semi-quantitatively assess the corrosion activity of the different microstructures, i.e., weld metal (WM), …

The Impact of Local Physiology on the Corrosion of Orthopedic Alloys
… were used to find the corrosion potential (Ecorr) and to determine the existence of a passive region. The Knee injury and Osteoarthritis Outcome Score for Joint Replacement (KOOSJR) was obtained at 3-11 months, 1-3 years, and 3+ years. Patients self-reported knee stiffness, pain, and …

Assessing and Enhancing Seawater Corrosion Performance of Aluminum Alloy 7075 and 2024 Additive Repairs Produced by Cold Gas Dynamic Spray Deposition
… error), but overaged CS-7075 has a less active Ecorr than wrought AA7075-T651 and in a repair scenario may cause a galvanic couple. Modifying spray processing parameters can cause significant changes in CS-2024 pitting performance without having a meaningful impact on potentiodynamic behavior. …

Investigation of Copper Pitting Propensity Using Bench and Field Scale Testing
… In addition to traditional approaches including ECorr rise, chlorine decay kinetics, and surface analyses, a novel method was attempted to develop "pitting currents" between copper samples exposed to differential flow. This method allowed pitting current, potential, and resistance between "pits" …

Investigating Synovial Fluid Electrochemical Properties Against Orthopaedic Alloys
… -0.38 and 0.15 V and corrosion potentials (Ecorr) values ranged between -0.95 and -0.2 V. Additionally, instantaneous corrosion rates (1/Rp) spanned nearly four orders of magnitude. For the second study, synovial fluid volumes from the TKA specimens were significantly higher than in native …

The Effects of Synovial Fluid and Inflammatory Cells on Orthopaedic Implant Alloys
… had lower OCP (p = 0.002), Rp (p = 0.013), and Ecorr (p = 0.012) values but higher corrosion rates (p = 0.03). No similar relationships were found for patients' SFs with TiAlV alloy implants. No differences in cell counts were found. The macrophages and supernatant were sent for ICPMS …

SITE FORMATION AND CORROSION PROCESSES: A Comparative Analysis of Condor and Stormy Petrel Wreck Sites
Submerged cultural resources abound in North Carolina waters, and two Civil War blockade runners built, launched, and sunk within months of each other provide an opportunity to review site formation processes through a multi-disciplinary lens. The incorporation of historical, electrochemical, …
