Special Issue Information

Dear Colleagues,

The success of our previous two editions of the Special Issue, titled “Corrosion Behavior and Mechanical Properties of Metallic Materials”, shows that the issues of corrosion are still relevant and require further research. Therefore, we are organizing a second edition of this Special Issue under the same title that will further present state-of-the-art advances in corrosion behavior and mechanical properties of metallic materials.

Worldwide, more than USD 400 million/year is spent on corrosion protection and productivity losses due to corrosion. Corrosion, a process associated with chemical/electrochemical reactions, often has a deleterious consequence on mechanical properties, ultimately resulting in the degradation of a material. Metallic components, widely employed in various industries, i.e., oil, gas, marine, nuclear, fuel cells, medicine and generate electricity, often suffer from severe corrosion, which might be detrimental to service life and even cause serious accidents. Meanwhile, some extreme corrosive environments are also the main restriction on applications of advanced metallic materials with excellent mechanical properties. Thus, understanding corrosion behavior and its effect on mechanical properties will be of great practical significance to the development and application of metallic materials. Corrosion behavior leads to the degradation of mechanical properties, and both are affected by the service environment and the physical and chemical properties of the material itself. 

The purpose of this Special Issue is to provide a research forum to report corrosion behavior as well as the related mechanical properties, chemical composition and microstructure for metallic materials to address existing corrosion challenges and assist in the development of super corrosion-resistant materials. 

Topics of interest include, but are not limited to, the studies mentioned above. Other relevant studies, such as hydrogen embrittlement, characterization of the corroded microstructure, corrosion mechanism of advanced materials, method of surface treatment to improve corrosion resistance, evolution mechanism of mechanical properties in corrosion environment, and design of novel corrosion-resistant material, will also be considered, which could enhance the knowledge of corrosion protection. Research articles and reviews in this area of study are welcome.

We look forward to receiving your valuable contributions.

In the aeronautics industry, high-strength steels such as AerMet 100 and 4340 are widely used in critical structural components that must withstand extreme operating environments. These materials possess high tensile strength, fracture toughness, and fatigue resistance. The aim of this investigation is to study the susceptibility to localized pitting corrosion of two aeronautics alloys, AerMet 100 and 4340, and their immersion in H2SO4, NaCl, and HCl solutions at room temperature, using electrochemical noise (EN) according to the ASTM ASTM-G199 standard. The EN signal was filtered by two different methods, and the polynomial method was employed to obtain Rn, LI, Kurtosis, Skewness, and the potential spectral density analysis (PSD). Results indicate that AerMet 100 exhibits lower corrosion rate—up to an order of magnitude lower than 4340. The resistance noise of 1599 Ω·cm2 in NaCl is higher. This same behavior is replicated when analyzing the noise impedance response (Zn). In conjunction with the analyses of PSD slope, it is reported that localized corrosion is the predominant mechanism in the evaluated environments. Full article

Developing stable alumina-based scales is critical for alumina-forming austenitic (AFA) alloys exposed to highly basic molten carbonates. However, the inherently sluggish diffusion of Al in austenite often limits the establishment of continuous protective layers. Herein, a thermomechanical treatment (TMT) strategy is proposed to enhance short-circuit diffusion pathways and promote selective Al oxidation in a Li–Na–K carbonate melt at 700 °C. After 90% cold rolling, annealing at 800 °C and 1000 °C generated two distinct microstructural states characterized by different grain boundary types, dislocation densities, and NiAl precipitate populations. The 800 °C-annealed alloy exhibits a significantly lower steady-state corrosion rate (~62 μm/yr) compared with the coarse-grained 1000 °C counterpart. EBSD and TEM analyses reveal that ultrafine grains, abundant low-angle boundaries, and finely dispersed NiAl precipitates provide efficient fast-diffusion channels and local Al reservoirs, enabling rapid formation of a continuous LiAlO2/Al2O3 inner layer. In contrast, insufficient Al flux in the 1000 °C microstructure results in extensive internal oxidation and growth of a thick, non-protective LiFeO2/NiO scale. These findings demonstrate that controlling the defect and grain-boundary structure via TMT is an effective route to overcome Al diffusion limitations and improve the molten-carbonate corrosion resistance of AFA alloys.

Laser powder bed fusion has attracted increasing attention for the production of metallic substrates intended for surface functionalization by advanced physical vapor deposition coatings. This study investigates the influence of the substrate manufacturing route on the performance of titanium–aluminum–silicon nitride-coated AISI 316L stainless steel, with particular emphasis on substrates produced by laser powder bed fusion. Conventionally manufactured and additively manufactured AISI 316L substrates were coated with a titanium–aluminum–silicon nitride layer using high-power impulse magnetron sputtering. The substrates were characterized by tensile testing and microhardness measurements, while coating thickness and uniformity were evaluated using the crater ball method. The mechanical integrity of the coating–substrate system was assessed by progressive load scratch testing. The additively manufactured substrate exhibited a significantly higher yield strength (411 MPa) compared to the conventionally manufactured material (257 MPa), together with increased microhardness. The titanium–aluminum–silicon nitride coating showed a uniform thickness of 4.47 µm and a well-defined coating–substrate interface. Scratch tests revealed a delayed onset of coating damage on additively manufactured substrates, with the transition to severe adhesive failure occurring at higher normal loads compared to the conventionally manufactured substrate. These results demonstrate that AISI 316L stainless steel produced by laser powder bed fusion provides a mechanically robust substrate for titanium–aluminum–silicon nitride coatings deposited by high-power impulse magnetron sputtering, with favorable coating response under progressive loading conditions.

This study aimed to investigate the influence of the synthesis parameters on the corrosion resistance of 3D-printed Inconel 718 components. Samples were fabricated using laser powder bed fusion (PBF-LB/M) with different angles of inclination. Corrosion tests were conducted by immersion for 1000 h in a 3.5% aqueous NaCl solution at 20 °C and 45 °C, and by the potentiodynamic polarization measurements. Detailed analysis of changes in morphology, chemical composition, and roughness of 3D prints was performed using scanning electron microscopy, combined with energy-dispersive X-ray spectroscopy, and optical profilometry. To quantify the dissolution of alloy components during the long-term measurements, the post-corrosion solutions were analyzed using microwave plasma–atomic emission spectroscopy. The obtained results demonstrate that inclination angle significantly affects corrosion rate and electrochemical kinetics, with measurable differences in mass loss, Icorr values, and surface degradation morphology observed between orientations. The findings indicate that build orientation governs microstructural anisotropy and surface characteristics, which in turn influence corrosion susceptibility. The novelty of this work lies in the systematic and multi-method evaluation of inclination angle as an independent structural parameter controlling corrosion kinetics in PBF-LB/M-fabricated Inconel 718, providing new insight into structure–corrosion relationships in additively manufactured nickel-based superalloys.

In this study, Inconel 600 alloy with reductions of 20%, 50%, and 80% was obtained through cold rolling, and the effects of plastic deformation on its mechanical properties and corrosion behavior in a hydrofluoric acid (HF) solution were systematically investigated. The results show that cold rolling induces pronounced work hardening, with both hardness and strength increasing continuously with increasing reduction, while the ductility decreases accordingly. The alloy with 80% reduction exhibits the highest strength, with an ultimate tensile strength of 1270 MPa and a yield strength of 1210 MPa. In contrast, the macroscopic corrosion resistance of the alloy in HF solution remains essentially unchanged with increasing deformation, although a slight intensification of pitting corrosion is observed. The combined effects of deformation-induced pitting and passivation enhancement resulted in retention of corrosion resistance. These findings demonstrate that appropriate control of cold rolling enables effective mechanical strengthening of Inconel 600 without significantly sacrificing its corrosion performance in aggressive fluorine containing environments.
