This study explores the formation and degradation mechanisms of the passive layer on laser powder bed fusion (L-PBF) processed Ni-Fe-Cr-based alloy 718 using high-resolution submicron analysis and microcapillary electrochemical techniques. The findings provide new insights into passive layer breakdown under tensile loading, revealing the influence of microstructural characteristics, dislocation distribution, and mechanical stresses. Tensile loading caused oxide layer cracking near cell boundaries with higher dislocation density. Detachment of the oxide layer from the matrix created voids, allowing aggressive ions to penetrate, promoting crevice corrosion. Cell boundaries remained mostly intact, as metallic particles within the surface oxide layer.

The effect of friction stir welding (FSW) on the microstructure and localised corrosion behaviour of the dissimilar weld of AA2099 T83 and AA2060 T8E30 alloys is investigated. FSW results in a drastic change in the microstructure thus altering their corrosion behaviour. The heat-affected region exhibits similar attack morphology to their respective base metal but is the most protected region. The stir zone (SZ) is the most susceptible to attack. During immersion of the entire weld, attack initiation occurs from the AA2060 SZ due to galvanic activity within the region caused by the overlap of the grains in the weld zone.

The microstructure and LBE corrosion behavior of the irradiated (up to 110 dpa) Fe15Cr11Al0.5Y coatings were investigated. The surface roughness and hardness increased with the irradiation dose. Irradiation induces grain growth, and the grown grains contain many dislocations, but no segregation and voids. Irradiation accelerates the corrosion rate of the coating, and the irradiated coatings suffer from serious inward non-uniform growth of the Al2O3 layer. The reaction of Al2O3 with PbO promoted the formation of the outermost PbAl2O4 of the irradiated coating. A “competitive mechanism” was proposed to explain the evolution of the corrosion behavior of the irradiated coatings.

(NiCrCo)82Ti9Al9 high−entropy alloy was attached to act as coating material by combining of laser cladding and laser remelting. In this study, the electrochemical properties of obtained HEA coatings were comparatively investigated using an electrochemical workstation, and the corrosion mechanism was revealed by the density functional theory calculations. The results show that the laser cladded HEA coating is mainly consisted of face-centered and body-centered cubic structures, and the face-centered cubic structure of the laser cladded HEA coating is transferred to the amorphous structure by laser remelting, which provides the stronger anti−corrosion capability compared with the face-centered cubic structure of HEA coating.

β-type Ti alloys have drawn extensive attention as potential metallic implants. In this work, the microstructure, corrosion behavior, and wear performance of Ti−17.3 Nb−1.8Fe (TNF) and Ti−22 Nb−30Zr−4Cr (TNZC) biomedical alloys were experimentally investigated, and CP−Ti and Ti6Al4V alloy were also used for comparisons. TNF and TNZC alloys after solution treatment at 1273 K showed a single β phase. It was found that TNF and TNZC alloys revealed better corrosion resistance than CP−Ti and Ti6Al4V alloy in different artificial saliva containing 0.15 wt% NaF with the pH values of 3.9 and 5.7, which could be ascribed to the formation of a double-layer passive film composed of multiple species oxides. Moreover, TNF and TNZC alloys exhibited higher wear resistance compared with CP−Ti and Ti6Al4V alloy, whose wear mechanism was adhesive wear and abrasive wear. The present results show that TNF and TNZC alloys are nice candidates for dental application.

Corrosion of lithium-containing AZ31 magnesium alloys AZ31-xLi (x = 4, 8, and 12 wt%) has been examined in 0.05 M NaCl solution with and without 10–150 mM of Na2MoO4 inhibitor. Potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and dynamic electrochemical impedance spectroscopy (DEIS) measurements were used to correlate the phase composition and microstructure of the alloys with their corrosion propensity and effectiveness of the molybdate inhibitor, giving high inhibition efficiency (>85%) at concentrations higher than ca. 35 mM. Post-corrosion microstructure, Raman, and X-ray photoelectron spectroscopy analyses allowed to provide the inhibition mechanism of AZ31-xLi alloys by molybdate ions.

WS2 is a two-dimensional nanomaterial with significant potential for hydrogen barrier applications. Herein, WS2/Ni composite coatings were fabricated on X70 pipeline steel substrates via electrodeposition. The properties of the composite coatings were systematically examined by electrochemical hydrogen permeation tests, hydrogen evolution kinetics tests, SSRT, SKPFM, and FEM. The results indicate that varying the deposition time leads to changes in coating microstructure, which correspondingly influence hydrogen permeation performance. Furthermore, the hydrogen barrier mechanism of the WS2/Ni composite coatings involves two key processes: the inhibition of hydrogen evolution reactions on the coating surface and hydrogen adsorption by WS2 within the coating interior.

Single pits were visually and electrochemically followed during their growth on a S41500 martensitic SS microelectrode. Solid particles were observed ejecting from the growing pit and after extraction, EDX determined they were mostly iron-based hydroxides/oxides. These particles were carried by fluid flow originating from the pit at a velocity of 21 μm/s. Finite element modeling confirmed the observed flow speeds are achievable by natural convection due to metal ion density gradients. While the pit solution does not experience flow, the bulk solution pH was observed to decrease illustrating how natural convection affects the bulk solution chemistry.

The coupling effect of hydrogen and NbCrN precipitate on pitting initiation and propagation of stainless steel were studied. After hydrogen charging, HMT results showed that more hydrogen was enriched on and around the precipitates. According to In-situ SKPFM and immersion results, the Volta potential of the precipitates is higher than that of the matrix before and after hydrogen charging. However, after hydrogen charging, a low Volta potential region appeared around the precipitates. The enrichment of hydrogen around the precipitates, the low potential around the precipitates, and consequent galvanic coupling effect lead to pits preferentially initiating and developing around the precipitates.

Special gases with trace moisture cause the formation of dynamic acidic microdroplets (DMD), which results in corrosion of semiconductor manufacturing devices. In this study, a predictive model for corrosion damage in 316L stainless steel (SS) was developed by combining the DMD process and the pitting initiation model. The DMD process was modeled using the BET model to describe the moisture-to-solution conversion. The pitting initiation model was reconstructed by incorporating the Sridhar model, temporal corrosion model, and Macdonald model. Finally, the predicted results were validated by various experimental data, indicating that the prediction model was accurate and highly reliable.
