Special Issue Information

Dear Colleagues,

Corrosion is well known to be a hazardous and tremendously expensive issue. The fundamental factor influencing how metal alloys behave when they corrode is surface interaction with the environment. Metals and alloys can be protected against corrosion using a variety of techniques, such as the application of coatings, the use of corrosion inhibitors, and cathodic/anodic protection. To prevent damaging issues in various industries, coating applications for corrosion control, protection, and prevention are becoming more and more popular today. Additionally, as metallic materials are used in a variety of industrial sectors, the development and promotion of new and enhanced surface treatments considerably contribute to new functionalities of metallic materials.

Even though corrosion inhibition has become a widely researched topic in recent years, the “Sustainable Development Goals” cannot be attained without more sophisticated understanding to win the war against corrosion and material deterioration. The dramatic effects of corrosion will undoubtedly be lessened with a profound comprehension of the corrosion inhibition phenomena.

In this regard, the present Special Issue aims to summarize and highlight the latest achievements in the literature, experimental work, and analytical techniques related to recent advances in the field of surface treatments and coatings applied to various metals and alloys to provide different functionalities. We encourage academic and industry researchers to submit high-quality original works on topics including, but not limited to the following:

  • Coatings for corrosion control in general;
  • Surface modification;
  • Chemical and electrochemical conversion treatments;
  • Most effective characterization and testing of surfaces before and after treatment;
  • Novel surface treatments involving green inhibitors.

To decrease energy consumption and improve the performance of micro-arc oxidation (MAO) films on 6063 Al alloy, a policy of K2TiF6 additive and electrolyte temperature control was adapted. The specific energy consumption relied on the K2TiF6 additive and more particularly on the electrolyte temperatures. Scanning electron microscopy demonstrates that electrolytes with 5 g/L K2TiF6 can effectively seal the surface pores and increase the thickness of the compact inner layer. Spectral analysis shows that the surface oxide coating consists of γ-Al2O3 phase. Following 336 h of the total immersion process, the impedance modulus of the oxidation film, prepared at 25 °C (Ti5-25), remained 1.08 × 106 Ω·cm2. Moreover, Ti5-25 has the best performance/energy-consumption ratio with a compact inner layer (2.5 ± 0.3 μm). This research found that the time of the big arc stage increased with the temperature, resulting in producing more internal defects in the film. In this work, we employ a dual-track strategy of additive and temperature providing an avenue to reduce the energy consumption of MAO on alloys. Full article
