Special Issue Information

Dear Colleagues,

Metallic materials are widely used in diversified sectors, such as chemical manufacturing, oil making and refining, the construction industry, machinery equipment, technological equipment and marine practices. While corrosion is a significant part of the destruction of manufacturing structures, a large number of investigations have been accomplished to find procedures to diminish corrosion and “wear costs”. The corrosion of metals and their alloys exhibits an appreciable economic and industrial concern. In industrial procedures, the metal surfaces employed are exposed to highly aggressive acids and alkali environments, which provoke substantial corrosion and deterioration.

Acidic and alkaline solutions are employed in a number of technological processes that currently cause severe metallic corrosion of varied metal structures and equipment in manufacturing environments. Some  explorations carried out for the protection of metallic materials in the  field of engineering  have determined that composite coatings are utilized as the most efficacious and simple way to hinder the deterioration of these materials in corrosive media. The application of inhibitors, using organic, metallic or inorganic coverings; cathodic and anodic defenses; electropolymerization methods; and nanostructured coatings are techniques for metallic materials’ anticorrosion protection.

The purpose of this Special Issue, "Corrosion, fatigue and corrosion protection of metals and their alloys in various environments" is to bring together and specify the various corrosion, fatigue and corrosion-endurance techniques, developments and applications from the perspective of the surface protection of diverse materials in different corrosive environments. In this Special Issue, original research articles and reviews are welcome.

  • Mechanisms and methods of corrosion control;
  • The principles and practices of metals and their alloys;
  • Theoretical and experimental study of organic and inorganic coatings for corrosion protection;
  • New developments in composite coatings and related materials;
  • Chemical and physical properties of organic and inorganic coatings and related materials;
  • Performance, investigation and analysis of various coatings;
  • High-performance experimental and processing coatings with exposure to high temperatures, high stress and different immersion times;
  • Corrosion, wear, fatigue and fracturing of metals and their alloys;
  • Computer modeling to provide protection, performance, stability and resistance properties in aggressive media.

Al-Si-Mg alloy has excellent casting performance due to its high silicon content, but the coarse eutectic silicon phase can lead to a decrease in its mechanical properties. Samples of AlSi10Mg alloy were prepared by using a spark plasma sintering method, and it was found that sintering temperature has a significant impact on the grain size, eutectic silicon size and wear and corrosion properties after heat treatment. At a sintering temperature of 525 °C, the alloy exhibits the best wear performance with an average friction coefficient of 0.29. This is attributed to the uniform precipitation of fine eutectic silicon phases, significantly improving wear resistance and establishing adhesive wear as the wear mechanism of AlSi10Mg alloy at room temperature. The electrochemical performance of AlSi10Mg sintered at 500 °C is the best, with Icorr and Ecorr being 1.33 × 10−6 A·cm−2 and −0.57 V, respectively. This is attributed to the refinement of grain size and eutectic silicon size, as well as the appropriate Si volume fraction. Therefore, optimizing the sintering temperature can effectively improve the performance of AlSi10Mg alloy. Full article
