Special Issue Information

Dear Colleagues,

Although it is true that progress in the issue of corrosion control and prevention has reached high levels of development, it is also true that this has generated areas of opportunity to continue searching alternatives to extend the useful life of an asset or good.

A metallic structure that is exposed in an environment tends to react with that environment, and given the above, various investigations have focused on trying to isolate the metal from the environment through anticorrosive coatings, and these include organic coatings, composite materials, metallic, thin films, and surface treatments; of equal interest are the application or deposit methodologies. On the other hand, it is important to highlight innovations with the additions of fibers, nanometric particles, with the aim of reinforcing their resistance to wear and erosion, and of course, “smart coatings”. Such a broad overview of the field of coatings has to do with its versatility and results in its use in various fields of industry with the lowest environmental impact.

This Issue is about making an impact with the UNESCO SDGs that focus on engineering for sustainable development, and it aims to address today's pressing issues and to promote a sense of global responsibility towards achieving these goals. It also focuses on necessary innovations, trying to provide a very important vision of the new challenges of the topic of coatings, as well as challenges with innovations in different industrial sectors and the conservation of historical metallic heritage.

This Special Issue focuses on works with the following concepts:

  • Theoretical and experimental research, knowledge and new ideas and trends in mechanisms of protective coatings against corrosion.
  • Recent developments in organic, inorganic and multifunctional hybrid coatings for use in all sectors from aerospace, medical, automotive and chemical industries to oil and gas technologies as well as historical metal heritage.
  • Coatings produced and applied through different processes, from traditional to the most high-tech, and whose objective is to control the phenomenon of corrosion and wear.
  • Understanding the mechanisms of electrochemical degradation of coatings due to corrosion or wear processes.
  • Use of Artificial Intelligence to predict the properties, performance, durability, and reliability of coatings in different environments.

Magnesium-based alloys are considered to be promising materials for the fabrication of temporary bone repair medical implants. The AZ31 magnesium-based (AZ31-Mg) alloy contains 3% aluminum and 1% zinc in its microstructure, which gives it mechanical strength and corrosion resistance. Nonetheless, the corrosion rate is high, which can lead to implant failure due to rapid degradation, which triggers the release of harmful metal ions. In the present work, a passive layer was obtained on the AZ31-Mg alloy, and subsequently, a cerium oxide (CeO2) coating was deposited through a chemical conversion treatment using 0.01 M CeO2 as a precursor. Based on X-ray photoelectron spectroscopy, the calculated amount of Ce(IV) and Ce(III) present in AZ31-Mg(OH)2/CeO2 was 93.6% and 6.4%, respectively. AZ31-Mg(OH)2/CeO2 showed improved corrosion resistance compared with the bare sample. The in vitro assessment of MC3T3-E1 pre-osteoblast cell viability showed that AZ31-Mg(OH)2/CeO2 was biocompatible after incubation for 24 and 72 h. The results revealed that the CeO2 coating confers greater electrochemical stability and biocompatibility properties, mostly due to the presence of Ce4+ ions. Full article
