Summary: The effects of laser shock peening (LSP) on the electrochemical and long-term immersion corrosion behaviors of AISI 420 martensitic stainless steel in a 3.5 wt% NaCl solution were studied. The results showed that LSP treatment significantly improved the corrosion resistance of the steel, with a decrease in passive current density and an increase in pitting potential. The LSP treatment also resulted in the formation of a Cr-rich passive film with better corrosion resistance, and the inhibitory effects of nanocrystalline structure and compressive residual stress effectively prevented rust formation even after 30 days of immersion.

Summary: Addition of Nb alloy significantly influences the passive film and corrosion behavior of the CoCrFeMnNi high entropy alloy (HEA), leading to refined grain size, promotion of Laves phase precipitation, and changes in inclusion type. The improved corrosion resistance, demonstrated by increased pitting potential and polarization resistance, is attributed to the alteration of passive film properties due to Nb alloying. Discussion on the relationship between microstructure, passive film, and corrosion property helps illustrate the corrosion enhancement mechanism brought about by Nb alloying.

Summary: The effects of different surface conditions, namely carbonaceous residue, copper chloride, and deposit, were quantitatively evaluated for their impact on localized corrosion. Electrochemical analysis and corrosion simulation showed that all three surface conditions induced localized corrosion on copper, with the pitting factor increasing in the order of deposits, copper chloride, and carbonaceous residue. Corrosion simulation further revealed that the galvanic corrosion current density increased as the surface coverage and density of chloride residue decreased.

Summary: The pitting corrosion susceptibility of 904L stainless steel in aerated LiBr solutions was studied using electrochemical measurements. The experimental variables, including electrolyte concentrations, pH, scan rate, temperature, and constant potential, were investigated. The results showed that the uniform corrosion rate and pitting corrosion susceptibility increased with increasing LiBr concentrations and temperature. Increasing the pH of the solution decreased both corrosion rates. An increase in scan rate enhanced uniform corrosion but suppressed pitting corrosion. EIS diagrams displayed a depressed semicircles with the center under the real axis. Bode plots supported the result that the uniform corrosion resistance decreased with increasing Br- anion concentration in LiBr solutions. The observations suggested that the observed single time constant may actually be the overlap of two time constants.

Summary: The influences of laser shock peening (LSP) with different coverage layers on the electrochemical and long-term immersion corrosion behaviors of 2Cr12NiMoWV martensitic stainless steel in 3.5 wt% NaCl solution were studied. LSP-induced corrosion resistant surface resulted in significant diminution of corrosion density and passive current density, as well as higher pitting potential. LSP-generated carbide decomposition, matrix nanocrystallization and surface segregation of Cr contributed to the generation of Cr-rich passive film with better corrosion resistance. Due to the inhibitory effect of matrix nanocrystallization and compressive residual stress on corrosion propagation, LSP greatly reduced the size and number of the corrosion pits even after 30 days' immersion in NaCl solution.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.

Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.

Summary: This study presents a new approach to studying the mechanism of filiform corrosion in organic coated steel using the scanning vibrating electrode technique (SVET) and micropotentiometry (potentiometric SECM). The electrochemical activity under the coating was evaluated by mapping the ionic current densities coming from artificial defects made in specific locations of the filament. Antimony tips were also used to investigate the pH changes associated with different corrosion reactions at the metal-paint interface. Local pH levels along the filament in the anodic and cathodic regions were determined.
