Special Issue Information

Dear Colleagues,

Tribology and corrosion are critical fields in materials science, impacting the longevity and performance of engineering components in various industries. Tribological characterization involves studying friction, wear, and lubrication, while corrosion characterization focuses on the degradation of materials due to chemical reactions with their environment. Advanced materials and coatings are being developed to enhance the durability and functionality of components, making research in these areas increasingly important. Understanding and improving the tribological and corrosion properties of these materials is essential for advancing technology and ensuring the reliability of systems in demanding applications.

We are pleased to invite you to contribute a paper to a Special Issue of Coatings titled "Tribological and Corrosion Characterization in Advanced Materials and Coatings". We aim to gather a collection of at least 10 high-quality articles that provide significant insights into this research area. If this target is met, this Special Issue may also be published in book form, offering a valuable resource for researchers and practitioners in the field.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Novel materials and coatings for improved tribological performance;
  • Corrosion-resistant materials and coatings;
  • Advanced characterization techniques for tribology and corrosion;
  • Mechanisms of wear and corrosion in advanced materials;
  • Tribological and corrosion behavior of nanomaterials and composites;
  • Surface engineering and modification techniques;
  • Environmental effects on tribological and corrosion properties;
  • Computational modeling and simulation of tribological and corrosion processes;
  • Case studies and industrial applications of tribological and corrosion research.

We look forward to receiving your contributions.

We would like to express our sincere thanks to Mr. Guoqing Wang from Nanjing University of Aeronautics and Astronautics, China, for his time and effort in contributing to this Special Issue.

By adjusting NiCr target power, five CrNiBN coatings with different Ni contents were fabricated on 45 steel by magnetron sputtering with the aim of improving corrosion resistance of CrBN coatings in seawater. The structure and morphology of CrNiBN coatings were characterized by X-ray diffraction and scanning electron microscope, while its electrochemical properties were evaluated by open circuit potential, electrochemical impedance spectroscopy, and potential dynamic polarization. The results demonstrated that Ni incorporation could reduce the surface porosity of CrBN coatings from 16.8% to 7.7% as Ni content increased from 4.35 at% to 19.62 at%. On this basis, when Ni increased from 4.35 at% to 7.28 at%, self-corrosion potential gradually increased, which prompted the CrNiBN coating with 7.28 at% Ni to present the highest charge transfer resistance Rct of 1.965 × 104 Ω·cm2 and the highest polarization resistance Rp of 74.9 kΩ·cm2. However, more Ni doping from 12.54 at% to 19.62 at% would decrease self-corrosion potential and trigger oxidation. Consequently, the CrNiBN coatings with Ni content from 12.54 at% to 19.62 at% presented decreasing Rct and Rp. Even so, the corrosion resistance of the CrNiBN coating was still better than that of CrBN coating indicating an improved corrosion inhibition efficiency by 12.53 times. Full article

The development of power engineering requires the introduction of new materials and technologies to improve the quality and durability of products. One promising direction is the creation of heat-protective coatings for the protection of working surfaces of turbine blades of gas turbine engines operating at temperatures up to 1000–1200 °C. Intermetallic coatings based on iron aluminides (Fe3Al, FeAl) have high resistance to oxidation due to the formation of an oxide layer: Al2O3. However, their application is limited by brittleness due to the so-called third element effect, which can be reduced through alloying with chromium. In this study the processes of formation of Fe–Al–Cr intermetallic coatings produced by air plasma spraying and the mechanisms affecting their stability at high temperatures were investigated. Experimental studies included the analysis of the microhardness, wear resistance, and corrosion resistance of coatings, as well as their phase composition and microstructure. The results showed that the optimization of sputtering parameters, especially in the FrCrAl (30_33) mode, promotes the formation of a coating with improved tribological and anticorrosion characteristics, which is associated with its dense and uniform structure. These data have an important practical significance for the creation of wear-resistant and corrosion-resistant coatings applicable in power engineering. Full article
