Special Issue Information

Dear Colleagues,

Since the appearance of stainless steels during the 1910s and 1920s, the number of applications for these alloys has grown enormously. Today, stainless steels and single crystal superalloys are gaining favor with designers in a plethora of industries, where they are required to meet high mechanical performance and appropriate corrosion resistance. The resistance to corrosion is paramount, as the costs of maintenance and the risk of accidents increase with the uses of alloys in increasingly more demanding environments.

This Special Issue is focused on the use of stainless steels and superalloys in highly demanding environments as well as novel corrosion protection measures to prevent or delay the corrosion process. Topics of interest include corrosion behavior in demanding environments, environmental assisted cracking of alloys, surface modifications, and use of coatings or novel inhibitors.

In this study, Al5083 alloy was deformed through equal-channel angular pressing (ECAP) up to three passes. The ECAP was conducted at room temperature in a mold using route C. The microstructure evolution was investigated under optical microscopic observations. The grain size was measured using ImageJ software. Grain refinement from 145 µM (as received) to 37 µM (after third pass) was observed due to ECAP. The potentiodynamic polarization of the Al5083 alloy was obtained from a 3.5% sodium chloride solution. Electrochemical impedance spectroscopy was performed in the sodium chloride solution to study the alloy’s surface properties. Scanning electron microscopy and Raman spectroscopy were conducted after obtaining the corrosion performance. As a result, we found that ECAP processing leads to the grain refinement of the alloy, which causes a detrimental effect on the corrosion resistance property. Full article

Sulphate reducing bacteria (SRB) can be found in alkaline environments. Due to their metabolite products such as hydrogen sulphide, the corrosion behaviour of materials in alkaline environments may be affected by the presence of SRB. This study focuses on the investigation of corrosion behaviour of duplex stainless steel DSS 2205 in nutrient rich artificial seawater containing SRB species, Desulfovibrio vulgaris, at different alkaline conditions with pH range from 7 to 10. The open circuit potential value (OCP), sulphide level and pH were recorded daily. Confocal laser scanning microscopy (CLSM) was used to study the adhesion of SRB on the DSS 2205 surface. Electrochemical impedance spectroscopy (EIS) was used to study the properties of the biofilm. Potentiodynamic polarization was used to study the corrosion behaviour of material. Inductively coupled plasma mass was used to measure the concentration of cations Fe, Ni, Mo, Mn in the experimental solution after 28 days. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were used for surface analysis. The results showed that D. vulgaris are active in an alkaline environment with pH 7–9. However, at pH 10, D. vulgaris activity exhibited an 8-day lag. The corrosion rate of DSS 2205 at pH 9 was higher than at other pH environments due to a higher dissolved concentration of hydrogen sulphide. Full article

Reinforced steel bars (rebar) are extensively used in construction, and the main challenge is in minimizing corrosion due to oxide or passive layer breakdown. In contrast, dual-phase (DP) steel has good corrosion resistance. This study investigated the effect of Cl ions on the electrochemical corrosion behavior of DP rebar and conventional rebar. Corrosion behavior studies and electrochemical measurements were conducted on DP rebar and conventional rebar in simulated concrete pore solution with different concentrations of Cl ions. Microstructure analysis, surface morphology analysis, and corroded surface characterization were performed using optical microscopy, field emission scanning electron microscopy, and Raman spectroscopy, respectively. Potentiodynamic polarization and electrochemical impedance spectroscopy measurements revealed that DP rebar has good passivity, leading to better corrosion resistance and greater strength compared to ordinary rebar. In addition, DP rebar showed better passivity behavior compared to conventional rebar in alkaline solution. Therefore, the presence of a dual phase (ferrite and martensite) in reinforced concrete structured steel induces good corrosion resistance. Full article
