Special Issue Information

Dear Colleagues,

This Special Issue of the journal—“Root Causes of and Preventative Measures against the Biodeterioration and Biocorrosion of Materials“—has a broad focus on understanding and predicting the core causes of the biocorrosion and biodeterioration of surfaces and concrete measures for preventing such damage to the surfaces of materials. Such a broad topic cannot be limited to a single discipline but must include many disciplines and a variety of expertise. On the one hand, we need scientists and engineers whose field of expertise includes material science and metallurgical engineering to pinpoint the weak spots of materials, which are the most susceptible to localized corrosion and pitting. On the other hand, we need chemists who understand the electrochemical processes that lead to accelerate localized deterioration of materials in relation to coating and material interfaces and their role in preventing or accelerating surface deterioration. We need expertise in microbiology, molecular biology and related disciplines in order to assess the roles of specific bacteria and their metabolites in biocorrosion and biodeterioration. We need expertise and experience in material science at the nanoscale to bridge the processes of the nano-world and the macro-world. Therefore, this Special Issue will bring together a wide range of disciplines to focus on a fairly specific objective: Identify what causes corrosion and biodeterioration and how can we prevent this from happening. A wide variety of techniques and combinations of them including improved metallurgy, coating with special polymers or mixtures of polymers and nanoparticles, and next-generation products that have not yet been investigated will be considered. If you feel your manuscript addresses any of these issues, we will be happy to consider publishing it.

In particular, the topics of interest include, but are not limited to:

  • Root causes of localized corrosion and preventative measures.
  • Coating of surfaces to prevent biotic and abiotic deterioration of coating materials and of underlying metallic or other surfaces.
  • Role of nanoparticles and their applications in material coatings to prevent corrosion and deterioration of materials such as concrete and carbon steel inside concrete.
  • The role of the metallurgical history of materials, metallurgical defects and inclusions in the localized corrosion of materials such as carbon and stainless steels and measures to prevent localized corrosion.
  • Next-generation non-corroding materials for replacing carbon steel and other steels for structural and pipeline applications.
  • Next-generation coating materials for preventing biotic and abiotic corrosion.

The influence of a direct current (DC) stray current on the corrosion and cathodic disbondment of X80 steel coated with a polyethylene (3PE) coating in 3.5% NaCl solution was studied by immersion experiments, electrochemical tests, three-dimensional microscopy, and a surface analysis. The results showed that the potential of the X80 steel sample shifts under the direct current. After 100A/m2 DC interference was applied, the potential of the sample in the anode region positively shifted from –0.68 to –0.43 V. At the same time, the sample in the cathode region negatively shifted to –1.45 V. Under the DC anode action, the X80 steel corrosion exhibited no passivation and followed Faraday’s law of electrolysis, in which the corrosion rate is proportional to the current density. Three-dimensional (3D) digital microscopy showed that, as the DC current increased, the depth of the corrosion pit also increased (gradually), indicating a higher corrosion degree. The sample in the cathode region only underwent a hydrogen evolution reaction, which caused cathodic disbondment of the coating. The stray current had a critical current density for the coating disbonding: the coating delamination area reached its maximum and then remained unchanged. Full article

Pyridine (P1) and benzoic acid (P2) derivatives with pyrazole moieties were synthesized and evaluated as corrosion inhibitors for mild steel in acidic medium. The evaluation was performed by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, and weight loss measurement. The surface morphologies of the control and steel samples coated with the pyrazole derivatives P1 and P2 were examined by the scanning electron microscopy (SEM), UV-Vis, and X-ray photoelectron spectrocopy (XPS) spectroscopies. Results revealed minor changes on steel surfaces before and after immersion in a 1 M HCl solution. Both derivatives, P1 and P2, showed good inhibition efficiency that is dependent on inhibitor concentration. Both P1 and P2 act as mixed-type inhibitors. The benzoic acid derivative (P2) showed a higher efficiency than P1, which could be attributed to the carboxyl group that is located at the para position to the amino group. This induces a direct electronic resonance between the two groups, the amino and the carboxyl. As a result of this, a higher electron density on the carboxyl group and a stronger bonding to the metal surface occurred. Results also show that, the bonding of both pyrazoles on mild steel surface obey Langmuir adsorption isotherm. Quantum chemical calculations were performed to theoretically define the relationship between the molecular structures and inhibition efficiencies of P1 and P2. Full article
