Special Issue Information

Dear Colleagues,

Coatings on materials are typically developed to improve their surface or interface properties under the service environment, such as anti-corrosion, anti-fouling, anti-wear, biocompatibility, etc. Coatings could prolong the lifetime of metals in various applications, such as coastal structures, chemical industries, military equipment, aerospace, and biomedical materials, by serving as physical protection layers or smart layers providing unprecedented functionality and opportunities for metallic substrates.

In recent decades, many exciting achievements in coatings for materials have been conducted. However, in some specific environments, challenges, for example, localized corrosion of materials and adaptive degradation of biomaterials, still remain to improve the corrosion resistance of materials and the controllability of biomaterials. Therefore, it is highly desirable to design and develop novel coatings with high environmental compatibility, low cost, and long-term durability towards excellent performance according to their application background. Towards this goal, we are assembling the Special Issue to encourage researchers to publish original articles, reviews, and short communication in this field. The topics of interest for this Special Issue include (but are not restricted to):

  • Novel coating design;
  • Corrosion/degradation mechanisms of metallic materials;
  • Novel eco-friendly coatings;
  • Surface treatment and functionality;
  • Bioactive coatings for metallic biomaterials.

High-entropy alloys have been widely used in engineering manufacturing due to their hardness, good wear resistance, excellent corrosion resistance, and high-temperature oxidation resistance. However, it is inevitable that metallurgical defects, such as micro cracks and micro pores, are produced when preparing the coating, which affects the overall performance of the alloy to a certain extent. In view of this situation, cavitation water jet peening (CWJP) was used to strengthen the AlCoCrFeNi high-entropy alloy coating. The effect of CWJP impact time on the microstructure and mechanical properties of CWJP were investigated. The results show that CWJP can form an effective hardening layer on the surface layer of the AlCoCrFeNi high-entropy alloy. When the CWJP impact time was 4 h, the microhardness of the surface layer of the specimen was harder than that of 2 h and 6 h, and the CWJP impact time had little effect on the thickness of the hardening layer. Observing the surface of the untreated and CWJP-treated specimens using the EBSD test, it was evident that the microstructure was significantly homogenized, the grains were refined, and the proportion of small-angle grain boundaries increased. The system reveals the grain refinement mechanism of the AlCoCrFeNi high-entropy alloy coating during plastic deformation. This study aims to provide a new surface strengthening method for obtaining high-performance AlCoCrFeNi high-entropy alloy coatings. Full article
