Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your work to this Special Issue entitled “Investigation on Structure and Corrosion Resistance of Steels/Alloys, 2nd Edition”.

Alloys/Steels are every important and key materials for engineering applications such as nuclear power plants, oil, chemical petrochemical, and marine industries. The mechanical and corrosion properties are the two most important properties of alloys/steels when working with them. Mechanical and corrosion properties are directly affected by microstructures. Thus, research on the microstructural, mechanical, and corrosive properties of alloys/steels is necessary for improving the properties of alloys/steels and is vital to develop advanced alloys/steels.

Previously, we set up the Special Issue entitled “Investigation on Structure and Corrosion Resistance of Steels/Alloys” (https://www.mdpi.com/journal/coatings/special_issues/structure_corrosion_resistance) with 14 publications. Based on previous success, we are glad to announce the second volume. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Localized corrosion of stainless steels;
  • Corrosion mechanism of ultra-high strength steels;
  • Advanced corrosion resistant coating of steels;
  • Structures of ultra-high strength steels;
  • Mechanical properties and corrosion resistance of high strength stainless steels.

We look forward to receiving your contributions.

In the CO2-amine solution system, metal packings in purification devices face corrosion risks, while plastic packings have garnered attention due to their lightweight nature, ease of processing, and excellent corrosion resistance. Since different plastic packings have varying applicable temperature ranges, exceeding their tolerance limits can significantly reduce their corrosion resistance. Therefore, selecting suitable plastic packings at different temperatures is crucial for ensuring safety. This study selected four plastic materials–PVC-C, PP, FEP, and PEEK–and systematically tested their performance indicators, such as volume, mass, strength, elongation, and thermal stability, in a CO2-amine solution system at experimental temperatures ranging from 60 to 130 °C. The experimental results show that PEEK outperformed the other three materials within the 60–130 °C range, making it suitable as a packing material for purification devices in high-temperature environments. Although FEP demonstrated good performance under the same conditions, its tendency to deform may limit its applicability. PP and PVC-C exhibited poor performance at high temperatures, with PVC-C particularly failing above 100 °C, rendering it unsuitable for high-temperature applications. This research provides important insights for the future selection of packing materials in CO2-amine solution systems for purification devices. Full article

The effects of X-doping (X = Mo, Ti, Ni) on the structure, stability, and electronic properties of B2-FeAl supercells, as well as the migration behavior of Cl atoms between interstitial sites and the corrosion behavior of FeAl coatings in molten chloride, were investigated by combining the first principles based on density functional theory (DFT) experiments. Our results confirmed that Mo and Ti atoms are more likely to replace Al atoms in B2-FeAl supercells, while Ni atoms preferentially replace Fe atoms. A single Cl atom is more inclined to be adsorbed at the tetrahedral (Tet) interstitial site of bulk B2-FeAl, and its formation energy Ef=− 2.504 eV, indicating that it can very easily invade FeAl alloys. (Mo, Ti, Ni) doping inhibited the diffusion of Cl atoms in the bulk B2-FeAl configuration and enhanced the corrosion resistance of the material to chlorinated molten salts, and Ti doping (overcoming the energy barrier by 0.326 eV) had the most obvious blocking effect. Based on the theoretical conclusions, this experimental study prepared an FeAl coating on 310S stainless steel with a Ni content of 20.22 wt.% at 800 °C for 15 h, which was then annealed at 900 °C for 25 h, and Ni was uniformly dissolved in the B2-FeAl phase. Subsequently, the annealed FeAl coating was corroded in molten chlorinated salts at 800 °C for 100 h, and an oxide layer with a thickness of 25–35 µm formed on the surface; the main components of this layer were Al2O3, NiFe2O4, and their solid solutions, which significantly improved the corrosion resistance of 310S stainless steel to chlorinated molten salt.

This study investigates the influence of micro-arc oxidation (MAO) duration on the formation and characteristics of ceramic coatings on 6061 aluminum alloys. MAO treatments were conducted in a silicate-based electrolyte for varying durations. The effects of oxidation time on film thickness, surface roughness, morphology, and phase composition were meticulously assessed using a film thickness gauge, surface roughness meter, scanning electron microscopy (SEM), and X-ray diffraction (XRD) analysis. The corrosion behavior of the coatings was evaluated in a 3.5% NaCl solution using an electrochemical workstation. The experimental results demonstrate that both the film thickness and surface roughness exhibit a positive correlation with oxidation time. Notably, the film growth rate initially increased before plateauing, suggesting an optimal oxidation duration. The coatings primarily comprise γ-Al2O3, α-Al2O3, and Al phases, with the proportions of γ-Al2O3 and α-Al2O3 increasing progressively with extended oxidation times. Comparative electrochemical tests revealed that the treated specimens exhibited significantly higher corrosion potential and reduced corrosion current densities compared to the untreated aluminum alloy substrate. Specifically, a coating produced with a 20 min oxidation time demonstrated an exceptional corrosion current density (Jcorr) of 1.545 × 10−6 A·cm−2 and a corrosion resistance (Rp) of 2.716 × 104 Ω·cm2, signifying the best corrosion resistance achieved in this study. These results underscore the pivotal role of oxidation time in tailoring the properties of micro-arc-oxidized layers on 6061 aluminum alloys, offering valuable insights for enhancing corrosion protection in practical applications.

In this study, we have prepared Ni-W/Cr3C2 composite electrodeposits through the diffuse reinforcement mechanism of chromium carbide nanoparticles. These electrodeposits exhibit excellent corrosion resistance and are designed to effectively protect the structural materials of pipe columns under the harsh CO2 corrosion environments faced by carbon sequestration and utilization technologies. A systematic investigation was conducted into the micro-morphology, profile undulation, phase composition, and surface chemical state of the electrodeposits. Furthermore, the corrosion-resistant behavior of Ni-W/Cr3C2 composite electrodeposits was investigated in simulated corrosive environments (i.e., brine solution containing 3.5 wt% NaCl and CO2-saturated brine). We then evaluated their corrosion response under the aforementioned conditions using electrochemical methods. In addition, the EIS of electrodeposited coatings revealed that the dense oxide film layer formed on the surface of the deposits, which acted as a primary barrier against corrosion, playing a pivotal role in maintaining the overall corrosion resistance of the material.

The corrosion–wear coupling damage failure of 8Cr4Mo4V bearing steel under marine atmospheric conditions significantly limits aeroengine bearing applications. The present work aims to investigate the evolution of the corrosion–wear properties of 8Cr4Mo4V bearing steel at varied corrosion intervals and estimate the corrosion–wear interaction (CWI) effect. Neutral salt spray tests combined with tribological experiments were employed to explore the effect of corrosion on wear and the influence of wear on corrosion, and a quantitative characterization method of corrosion–wear interactions was proposed by establishing the component relationships of material losses in the corrosion–wear process. The results indicate that the corrosion rates initially increase and then decrease, ultimately resulting in a pattern characterized by predominant total corrosion and nested localized corrosion. The corroded surfaces tremendously influence the friction coefficient curves at the third stage, and a synergistic acceleration effect exists in the CWI behavior of 8Cr4Mo4V bearing steel under the action of corrosion and wear. A sample corroded for 6 h displayed the significant facilitative effect of corrosion on wear, exhibiting the highest CWI ratio and a greater total mass loss primarily attributed to corrosion. This study offers a significant reference for the quantitative assessment of the tribo-corrosion properties of bearings in a marine atmospheric environment. Full article
