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.

Influence of Chloride Ions on Electrochemical Corrosion Behavior of Dual-Phase Steel over Conventional Rebar in Pore Solution

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
