Corrosion behavior of a compositionally complex alloy utilizing simultaneous Al, Cr, and Ti passivation

Samuel B. Inman et al.

Summary: The corrosion behavior of a compositionally complex dual-phase alloy, Al0.3Cr0.5Fe2Mn0.25Mo0.15Ni1.5Ti0.3, was investigated in different electrolytes. Despite lower Cr concentrations, comparable corrosion resistance to 316L stainless steel and Ni-Cr binaries was observed in NaCl. In-situ atomic emission spectroelectrochemistry and ex-situ X-ray photoelectron spectroscopy were used to identify the elemental fates during corrosion, indicating the enrichment of Al, Cr, Ti, and Mo in the passive film. Proposed benefits of Al-Cr-Ti coexistence were addressed.

The role of chromium content in aqueous passivation of a non-equiatomic Ni38Fe20CrxMn21-0.5xCo21-0.5x multi-principal element alloy (x=22, 14, 10, 6 at%) in acidic chloride solution

Angela Y. Gerard et al.

Summary: The effect of Cr content on corrosion behavior in multi-principal element alloys (MPEAs) and binary solid solution alloys was investigated. Passivity and localized corrosion resistance were obtained in MPEA and binary alloys with Cr content above a certain threshold. Cr cation enrichment was observed in the passive films, and its fraction correlated with the passive current density. The degree of Cr enrichment was influenced by thermodynamic and kinetic factors.

Understanding Tribocorrosion of Aluminum at the Crystal Level

Kaiwen Wang et al.

Summary: In this study, a crystal-based tribocorrosion modeling framework was developed based on experimental and computational investigations of Al single crystals. The effects of lattice reorientation and dislocations on surface corrosion were taken into account. The experimental results showed that the tribocorrosion rate was independent of the initial crystal orientations. A multiphysics finite element model was developed and successfully predicted the depassivation and repassivation currents during tribocorrosion. The decrease of orientation-dependence during tribocorrosion was explained in terms of the coupling between un-rotated and rotated lattices.

Spontaneous passivation of the CoCrFeMnNi high entropy alloy in sulfuric acid solution: The effects of alloyed nitrogen and dissolved oxygen

Xuejie Li et al.

Summary: In this study, the dissolution and passivation kinetics of CoCrFeMnNi high entropy alloys in an acidic solution were investigated. The alloy with nitrogen addition exhibited spontaneous passivation driven by dissolved oxygen, while the alloy without nitrogen required an acceleration of dissolved oxygen for passivation. The nitrogen containing alloy had a lower critical dissolution rate, leading to enhanced passivation efficiency.

Alloying effects in high temperature molten salt corrosion

Touraj Ghaznavi et al.

Summary: This study investigates the dealloying phenomenon of Fe-(Cr)-Ni model alloys in molten chloride salts that simulate the heat-transfer circuits of molten salt nuclear reactors. Classical dealloying with porosity formation is observed as the dominant form of corrosion at low temperatures. Additionally, the increased surface diffusivity of the more-noble element, Ni, in molten chloride salts decreases the critical parting limit for dealloying.

The Effect of Temperature on Dealloying Mechanisms in Molten Salt Corrosion

Touraj Ghaznavi et al.

Summary: The mechanism of molten salt corrosion of Ni- and Fe-based model alloys at different temperatures relevant to molten salt nuclear reactors has been studied. It was found that Fe and Cr alloy elements separate in molten chloride salts, which depends on temperature. At lower temperatures, the corrosion mechanism is similar to aqueous systems, while at higher temperatures, grain boundary corrosion becomes prevalent and lattice diffusion plays an important role. When the temperature exceeds 600 degrees C, the crystal orientation of the corroded material is no longer the same as its parent grain, and the corrosion becomes more one-dimensional.

Multiphysics modeling and uncertainty quantification of tribocorrosion in aluminum alloys

Kaiwen Wang et al.

Summary: The research developed a finite element based multiphysics model to analyze the synergistic effects of mechanical and corrosion properties on tribocorrosion degradation mechanisms. Residual stress near the wear track edge led to concentrated corrosion current, causing non-uniform surface corrosion and stress-corrosion coupling which affected the tribocorrosion rate. Predictive tribocorrosion rate maps were generated based on material properties, showing that metals with specific properties are most resistant to tribocorrosion.

Ultrahigh tribocorrosion resistance of metals enabled by nano-layering

Wenbo Wang et al.

Summary: The study demonstrated that nanostructured metallic multilayers (NMMs) exhibit ultrahigh tribocorrosion resistance due to abundant interfaces and nanoscale chemical modulation. The experimental and computational study provides guidance for future material selection and design of multilayered and multi-phase metals for use under extreme environment. Through nanolayering, the surface work function of Al was increased while Cl adatoms adsorb less strongly than that on pure Al, reducing surface reactivity and pitting susceptibility.

A comparative study on the critical pitting criteria of a super ferritic stainless steel at different temperatures in chloride or bromide solution

Longlin Lei et al.

Summary: The critical pitting criteria of S44660 in chloride or bromide solution were investigated. The study found that the more aggressive Cl- does not necessarily lead to lower Eb values in all temperature ranges. The Eb-T curves revealed that the pitting behavior can be divided into transpassivation, transition, and pitting regions with temperature. Further investigations showed that the wider transition region in bromide solution is due to the weakened repassivation ability caused by the interaction between Br- and Mo, indicating that pitting is more likely to occur at lower temperatures in bromide solution.

Multi-principal element alloys from the CrCoNi family: outlook and perspectives

Francisco G. Coury et al.

Summary: Great research effort is being employed in the development of Multi-Principal Element Alloys (MPEAs), focusing on the vast compositional field they exist in. Among the promising MPEAs, compositions containing large contents of Cr, Co and Ni, like the Cr33Co33Ni33 alloy, show outstanding combination of strength and ductility. The critical review in this work examines the history of MPEA development, phase equilibria, and main studies explaining the good mechanical properties of these alloys, highlighting grain refinement, solid solution strengthening, twinning, and transformation induced plasticity. The review also emphasizes the excellent properties of high Cr-containing alloys in terms of strength, ductility, corrosion resistance, and oxidation resistance, surpassing some Ni-superalloys.

Emergence of micro-galvanic corrosion in plastically deformed austenitic stainless steels

Xin Chen et al.

Summary: Localized plastic deformation has been found to make nuclear reactor components more susceptible to stress corrosion cracking (SCC). By analyzing the surface reactivity and corrosion behavior of deformed stainless steel specimens, research has shown that regions with higher dislocation concentrations exhibit increased reactivity due to a reduction in corrosion activation energy. The combination of surface reactivity and strain distributions suggests that SCC cracking is likely to occur in areas with localized strain where micro-galvanic corrosion is favored.

Enabling High-Performance Surfaces of Biodegradable Magnesium Alloys via Femtosecond Laser Shock Peening with Ultralow Pulse Energy

Wenbo Wang et al.

Summary: The application of femtosecond laser shock peening (fs-LSP) effectively improves the surface mechanical, corrosion, and tribocorrosion properties of WE43 magnesium alloys, enhancing their potential usage as biodegradable orthopedic implant materials. The combination of a black tape and a quartz layer under a power density of 28 GW/cm(2) was found to give the optimum peening effect, strengthening the surface and reducing corrosion kinetics simultaneously. The rapid self-repassivation observed in fs-LSP-treated WE43 surfaces during tribocorrosion promises sustained corrosion resistance under mechanical loading, critical for load-bearing implants.
