Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

Materials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.

High‐Efficiency Lithium Sulfur Cells With Suppressed Polysulfide Solubility Using a Cost‐Effective Ammonium‐Based Ionic Liquid Electrolyte

Small, EarlyView.
The cost‐effective ammonium‐based ionic liquid electrolyte, N₁₁₁3FSI, suppresses polysulfide dissolution to sub‐millimolar levels in lithium–sulfur batteries. The electrolyte promotes efficient FSI− anion reduction, forming a dense, LiF‐rich solid‐electrolyte interphase on both the lithium metal anode and sulfur cathode. This dual‐electrode passivation

Rational Design of LiNi1‐xFexO2 Electrodes for Enhanced Oxygen Evolution Reaction Under Power‐Fluctuating Operations in Alkaline Water Electrolysis

Small Methods, EarlyView.
We develop Fe‐incorporated LiNiO2 for the OER in alkaline media, where Fe enhances Ni3+ oxidation state and optimizes eg orbital filling, significantly improving activity under power fluctuations. ABSTRACT The electrochemical performance of alkaline water electrolyzers is hindered by power fluctuations when integrated with renewable energy sources in ...

Trends in the Electrochemical Polarization Potentiodynamic Reactivation Method – EPR

Chemical and Biochemical Engineering Quarterly, 2007
This method designed to examine the susceptibility to nonuniform corrosion, ranks among the more successful technique developments. One of its numerous advantages is that it allows nondestructive, on-site examination. EPR measurements are used to establish the resistance of stainless steels and alloys to intergranular corrosion and stress corrosion ...
