Special Issue Information

Dear Colleagues,

Ceramic coatings have garnered significant attention in many industries owing to their superior properties, including high hardness, wear and corrosion resistance, and superior protection in aggressive environments. They are also utilized in energy conversion and storage devices. Transition metal-based nitride, carbide, oxide, composite, and multicomponent ceramics have been widely employed as coating materials in various industries for over three decades. High-entropy ceramics have also garnered substantial industrial attention in recent years due to their exceptional physio-mechanical characteristics. Recent studies have emphasized our capacity to improve the microstructure of ceramic coatings via the addition of appropriate elements and adjusting process conditions to enhance the coating performance.

The aim of this Special Issue, entitled “Research Progress in Ceramic Coatings”, is to present state-of-the-art advancements in ceramic coatings for various industrial applications. Thus, we welcome papers on innovative advancements in functional ceramic coatings, including self-repairing, bioactive, and superhydrophobic coatings. These coatings have potential applications in various industries, such as the biomedical, automotive, aerospace, and energy sectors. Papers that address the optimization, characterization and evaluation of the comprehensive properties of advanced ceramic coatings deposited using various coating techniques including PVD, CVD, sol–gel, as well as thermal spray methods are welcome in this Special Issue. We also welcome papers related to the challenges and future perspectives of advanced ceramic coatings, and those enhancing their performance and exploring new applications.

The development of advanced thermal barrier coating (TBC) materials with better hot corrosion resistance, phase stability, and residual stresses is an emerging research area in the aerospace industry. In the present study, four kinds of TBCs, namely, single-layer yttria-stabilized zirconia (YSZ), single-layer gadolinium zirconate (GZ), bilayer gadolinium zirconate/yttria-stabilized zirconia (YSZ/GZ), and a multilayer functionally graded coating (FGC) of YSZ and GZ, were deposited on NiCrAlY bond-coated nickel-based superalloy (Inconel 718) substrates using the atmospheric plasma spray technique. The hot corrosion behavior of the coatings was tested by applying a mixture of Na2SO4 and V2O5 onto the surface of TBC, followed by isothermal heat treatment at 1273 K for 50 h. The characterization of the corroded samples was performed by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) to identify physical and chemical changes in the coatings. GIXRD was used to analyze the residual stresses of the coatings. Residual stress in the FGC coating was found to be −15.2 ± 10.6 MPa. The wear resistance of TBCs is studied using a linear reciprocating tribometer, and the results indicate that gadolinium zirconate-based TBCs showed better performance when deposited in bilayer and multilayered functionally graded TBC systems. The wear rate of as-coated FGC coatings was determined to be 2.90 × 10−4 mm3/Nm, which is lower than the conventional YSZ coating. Full article
