Special Issue Information

Dear Colleagues,

Corrosion deterioration of materials in the industry is a major problem affecting economic, safety, and logistical issues. Metals and alloys such as titanium, aluminum, superalloys, and stainless steels have found an increasing application in various industrial components that require high mechanical strength, and good resistance to corrosion.

The aerospace, biomedical, chemical, and petro-chemical industries demand improvements in structural and functional material components based on scientific research carried out on new materials and corrosion protection methods. The intrinsic strength of alloys is not sufficient to protect structural components exposed to aggressive environments. In both cases, this can be achieved by the optimization of alloy design and metallurgical processes, and by appropriate corrosion control strategies, such as novel pretreatments and coating designs for low-temperature applications and cromate-free coatings, among others, which will help to extend the life of service of metallic components.

This Special Issue on Electrochemical Corrosion and Protection of Steels and Alloys focuses on current trends in electrochemical corrosion science, engineering, and technology and aims to cover recent research studies related to metal and alloy performance used in the industry, addressing electrochemical techniques, corrosion protection methods, corrosion mechanisms, simulation and modeling, as well as failure analysis case studies. All articles related to the broad spectrum of materials behavior used in industry and corrosion protection methods are welcome. We hope that this Special Issue will provide useful information for the scientific community working in this exciting field of corrosion.

This study conducts a comparative electrochemical evaluation of three types of pearlitic steels used in flexible pipelines for oil transport in marine environments. The steels have been manufactured with chemical composition and geometry variations to optimize operation performance under adverse conditions. Electrochemical tests were conducted using solutions simulating marine environments with NaCl and CO2, and at high temperatures. The results indicated that spheroidized (SC) steel demonstrated the best corrosion resistance under these specific conditions. Additionally, the Raman spectroscopy characterization technique was used to analyze the layers of corrosion products formed during the tests, identifying the presence of FeCO3 (siderite) and other corrosive oxides. These discoveries are valuable for selecting and improving materials in flexible pipelines used in oil production in marine waters. The study highlights the importance of the cementite morphology present in pearlite as a relevant factor in the corrosive behavior of steels, contributing to the development of more efficient and durable solutions for the offshore oil and gas industry.

The corrosion fatigue behavior of a martensitic stainless steel AISI 410 with 12% Cr, used in the fabrication of steam turbine blades at low pressure (L-P), was studied using the electrochemical noise technique (EN) under mechanical fatigue (immersion and aired) conditions. The tests were done in a simulated environment using four levels of mechanical stress (Δσ) in a 3 wt.% NaCl solution at 90 °C. The specimens underwent pitting corrosion when exposed to the corrosive environment; afterwards, such pits generated mechanical strength sites over the metallic surface, facilitating the initiation and propagation of cracks, which was already enhanced by the applied cyclic loads. From scanning electron microscope (SEM) images, it was possible to observe localized plastic deformation. In such instances, the fatigue damage was caused by the microplasticity (μ), i.e., the shear strength, resulting from the breakdown of the passive layer that was subjected to mechanical load, which led to a significant increment of the velocity of crack propagation, and therefore, a decrement of the useful life of the material. The obtained results show that the fatigue resistance limit in the corrosive medium was lower than that observed in aerated conditions due to the sum of the effects of mechanical fatigue and corrosion.
