Special Issue Information

Dear Colleagues,

Effectively prolonging the service life of metal materials in industrial applications is still a significant and urgent issue and one of great challenge. Functional coatings, such as self-healing coatings, superhydrophobic coatings, and lubricant-infused coatings, have attracted great attention in the field of corrosion protection in recent decades. In addition, the investigation of corrosion monitoring and corrosion protection mechanisms can fundamentally help us to improve the corrosion protection performance of the aforementioned coatings. The topics of interest for this Special Issue include (but are not limited to) the following:

  • Anti-corrosive coatings;
  • Self-healing coatings;
  • Superhydrophobic coatings;
  • Lubricant-infused coatings
  • Corrosion monitoring;
  • Surface and interface characterization;
  • Corrosion protection mechanism;

We look forward to receiving your contributions.

Hopeite (Zn3(PO4)2·4H2O) coatings, fabricated via zinc phosphate chemical conversion (ZPCC), have attracted considerable interest in biomedical applications owing to their excellent corrosion resistance and biocompatibility. However, the influence of calcium nitrate (CN) on coating properties remains poorly understood. This study systematically investigates the effect of CN concentration on the microstructure and corrosion behavior of ZPCC coatings deposited on stainless steel (SS). The phase composition, surface morphology, and elemental distribution were characterized using X-ray diffraction (XRD) and scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS). Electrochemical corrosion performance was assessed via potentiodynamic polarization in a 0.9 wt.% NaCl solution. The results indicate that CN concentration critically influences coating morphology, with higher concentrations leading to reduced crystal size and increased coating mass. Notably, the coating prepared with 6 g/L CN exhibited a dense, uniform, and fine-grained microstructure, resulting in superior corrosion resistance. Additionally, the optimized coating demonstrated strong interfacial adhesion, with a shear strength of 10.05 ± 1.2 MPa. Full article
