Special Issue Information

Dear Colleagues,

In harsh environments (such as deep-sea, high-temperature and high-pressure, strong chemical, high salt spray, and industrial corrosive gas environments, among others), the corrosion of metallic materials directly threatens engineering safety, increases economic costs, and restricts technological applications. This Special Issue, “Corrosion Mechanisms and Protection Technologies of Metallic Materials under Harsh Environments”, focuses on cutting-edge research in the field of metallic corrosion protection in harsh environments. The included articles cover innovative achievements in areas such as metallic corrosion mechanisms, new protective coatings, and new corrosion inhibitors.

This Special Issue aims to provide new ideas and solutions for addressing the increasingly severe corrosion challenges—especially those in harsh environments like oil and gas, deep-sea, marine atmosphere, high-temperature, and chemical engineering environments. It is also committed to building a platform for researchers to showcase the latest progress in novel coating technologies and theoretical elaborations. We welcome submissions of original research papers, review articles, and short communications.

Potential topics focus on the field of materials chemistry, covering a wide range including but not limited to the following areas:

  1. Corrosion mechanisms of metallic materials in deep-sea and marine atmospheric environments;
  2. Corrosion mechanisms of metallic materials in extreme oil and gas environments;
  3. Corrosion mechanisms of metallic materials in extreme chemical process conditions;
  4. Corrosion mechanisms of metallic materials in high-temperature power environments;
  5. Synthesis, design, and application of novel corrosion inhibitors;
  6. Design, preparation, and performance evaluation of novel coatings.

In this study, Cr/CrN and Mo/MoN alternating multilayer coatings with pure metal interlayers were deposited on 316 L stainless steel substrates via physical vapor deposition to systematically investigate the corrosion resistance, wear resistance, and tribocorrosion behavior of the multilayer coating systems in physiological saline environments. Microstructural characterization revealed that the CrN layer consists of mixed CrN and Cr2N phases, whereas the MoN layer exhibits a highly densified microstructure along with the presence of MoO2 phase, which collectively contribute to the superior corrosion resistance of the Mo/MoN coating. Furthermore, compared to the CrN layer, the MoN layer demonstrates enhanced nanomechanical properties and improved resistance to crack initiation, due to the greater hardness and higher H/E and H3/E2 values. Consequently, the Mo/MoN coating exhibits significantly better wear and tribocorrosion performance than its CrN counterpart. This work provides a theoretical foundation for the design of tribocorrosion-resistant hard coatings for artificial joint materials. Full article

This study aims to clarify the influence of H2S concentration and temperature on the sulfide stress corrosion cracking (SSCC) susceptibility of 20# steel weld joints. 20# steel is a commonly selected pipe material for ground gas pipelines, and there is a risk of welds cracking after years of service. The selection of a corrosive environment is based on the working conditions of high-sulfur oil fields on site. Slow strain rate tensile (SSRT) tests were conducted under simulated high-sulfur gathering and transportation conditions across varying temperatures and H2S concentrations. The mechanical properties, SSCC susceptibility, fracture morphology, and elemental composition of fracture surfaces were systematically analyzed. As H2S concentration increased (5%, 7.5%, 10%) and temperature decreased (30–60 °C), the elongation after fracture and the reduction in area of 20# steel decreased, while the yield strength and SSCC susceptibility increased. The H2S concentration range of 0–5% represented a critical sensitivity interval for the material, where elongation after fracture decreased by up to 74%. Within the 5–10% H2S range, elongation decreased by only 2.11%, indicating a slowing trend of fracture toughness deterioration, though SSCC susceptibility still increased by 12%. Increasing the temperature from 30 °C to 60 °C reduced SSCC susceptibility by approximately 30%, confirming higher susceptibility at lower temperatures. Temperature exerts a lesser influence on material performance than H2S concentration. Also, 20# steel remains within the SSCC brittle fracture sensitivity zone in sulfur-containing environments, necessitating strict quality control to avoid defects and stress concentrations. In high-sulfur environments (H2S > 5%), further increases in H2S concentration have a diminished effect on cracking susceptibility. Full article
