Special Issue Information

Dear Colleagues,

The process of identifying the elements that lead to corrosion or rust on metals after exposure to typical atmospheric conditions is known as corrosion detection. This is essential for determining the materials' ability to withstand the existing environmental factors and vital in identifying the strength of materials before use in building, construction or any other operation.

Corrosion can be one of the biggest threats to the longevity of metals. It can pose safety risks to people working with metallic objects, huge equipment costs, and subsequent environmental damage. However, through its detection, it is possible to determine, examine and predict the strength and durability of the materials in use. This is why surface degradation monitoring and rust detection are so important. They help mitigate these risks and expenses by preventing the degradation of metallic surfaces over time, allowing problems to be addressed before they reach a critical point. It also improves safety, reduces costs and increases the efficiency of the monitored structures.

Based on all this, the suggested scope of this Special Issue includes (but is not limited to) the following concepts:

  • Advanced corrosion detection and monitoring techniques;
  • Improved knowledge of corrosion protection of steel surfaces;
  • Intelligent industrial corrosion monitoring technology online;
  • Novel anti-corrosion coatings or surface treatments with improved durability;
  • New protection techniques of metals in extreme environments and conditions;
  • Corrosion detection data information system.

Abstract
Buried piping is subject to soil corrosion, which can be prevented by combining coatings and cathodic protection to maximize corrosion control. However, even with both methods, coatings are subject to damage from external factors and various causes. Buried piping may expose the metal [...] Read more.
Buried piping is subject to soil corrosion, which can be prevented by combining coatings and cathodic protection to maximize corrosion control. However, even with both methods, coatings are subject to damage from external factors and various causes. Buried piping may expose the metal and alter the current flow, which in turn causes corrosion. Therefore, this study analyzed the effect of detection electrode spacing on the direct current voltage gradient (DCVG) magnitude formed for coated pipelines buried in the soil. The DCVG was measured using a real-time coating defect detection system. FEM model simulations were carried out, and then the result was compared to the measured DCVG magnitude. When the spacing of the detection electrodes increased, the detected signal and signal location changed. The detection reliability increased as the noise signal is eliminated at the optimum detection electrode spacing. However, the detection reliability decreased at higher selection electrode spacing as the noise signal and detected signals together were eliminated. The location of the detected signal shifted as the spacing of the detection electrodes increased due to the change in the detection reference point and signal magnitude. Full article

To address rebar corrosion in existing concrete structures, a multifunctional compound rust inhibitor was developed. This study investigates the impact of this inhibitor on carbon steel rust resistance, as well as the mechanical properties and durability of concrete. The results demonstrate a significant reduction in weight loss of carbon steel when using a multifunctional rust inhibitor, with a rust inhibition efficiency of 82.6%. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) were employed to observe and analyze the surface elements of carbon steel, both with and without the presence of a rust inhibitor. The findings indicate that the use of a rust inhibitor leads to a smoother and more stable surface film. The results of the experiments on compressive strength, chloride ion electromobility, and the rapid carbonation test of concrete with varying rust inhibitor contents indicate that increasing the amount of rust inhibitor can improve the compressive performance of concrete and can regulate the mobility of chloride ions. Specifically, when the rust inhibitor content reaches 4%, it has a notable positive impact on the performance of concrete, and further increases in content lead to smoother results. Full article
