Special Issue Information

Dear Colleagues,

Light alloys have received considerable interest for applications in the military, automotive, aerospace, sports, electronics, as well as biomedical industries, owing to their low density accompanied by interesting mechanical properties such as high strength-to-weight ratio. However, their wider application has been limited due to the relatively poor surface properties. Moreover, surface properties of aluminum, magnesium, and titanium light alloys can considerably influence the functional performances of these light alloys. Surface coating is an effective and economic way to protect light alloys from corrosion, wear, and oxidation. In fact, protective coatings (with high bond adhesion strength) should provide a barrier between the bare metal and the catastrophic environmental conditions. This will change the surface properties of the workpiece and should lead to the enhancement of service life of the component as well. Wide research activities have been performed to develop advanced surface engineering methods for light alloys.

The objective of this Special Issue is to present the latest experimental and theoretical developments in this field, through original research and short communication papers, and review articles from academic and industries around the world.

In particular, the topics of interest include but are not limited to:

  • Protective coatings on light alloys for biomedical applications, antibacterial/antifouling/antiviral purposes;
  • Protective coatings on light alloys for corrosion protection;
  • Protective coatings on light alloys for improvement of oxidation resistance;
  • Protective coatings on light alloys for improvement of wear resistance;
  • Protective coatings on additively manufactured light alloys.

Plasma electrolytic oxidation (PEO) has attracted increasing attention since the transportation industry adopts more lightweight metal components and requires an improved version of anodizing for surface protection. In response to the demand, researchers enrich the technical connotation of PEO through diversifying the growth paths and adopting new precursors. Foreign electrolyte additives, involving ceramic and polymeric particles, organic dye emulsions, are incorporated to accomplish various goals. On the other hand, significant progress has been made on comprehension of softening sparks; denoting the adverse trend of growing discharge intensity can be re-routed by involving cathodic current. IV response shows the cathodic pulse current not only cools down the ensuing anodic pulse, but also twists the coating conductivity, and the residuals of twists accumulate over a long time frame, plausibly through oxide protonation. Thus, the cathodic current provides a tool to control the discharge intensity via integration of the coating conductivity deviations. So far, these cathodic current studies have been performed in the electrolytes of KOH and Na2SiO3. When exotic additives are included, for example Cr2O3, the cathodic current effect is also shifted, as manifested in remarkable changes in its current–voltage (IV) behavior. We anticipate the future study on cathodic current influences of inclusion shall lead to a precise control of micro arc. Full article
