Special Issue Information

Dear Colleagues,

Recent developments in high-performance coatings fabricated on metallic substrates by chemical vapor deposition (CVD) and physical vapor deposition (PVD) technologies have had a significant impact on the field of surface engineering for a wide range of applications including aerospace, automotive, defense, chemical processing, renewable energy, and medical devices. While traditional CVD and PVD coatings are primarily to provide substrate protection against wear, corrosion, and oxidation, or impart new properties to the substrate surface, today’s CVD and PVD coatings can offer advanced functionalities such as in situ performance monitoring, adaptive properties, and self-healing. These advancements are largely achieved by utilizing novel deposition processes, e.g., plasma-assisted CVD (PA-CVD) and high-power impulse magnetron sputtering (HIPIMS), to produce nanostructured, multifunctional films with unique properties. Equally noticeably, recent progress in modeling, characterization, and testing has facilitated the discovery of new coating compositions tailored to specific applications.

In this Special Issue, original research papers and review articles are welcome. Research topics may include but are not limited to the following:

  • Novel CVD and PVD processes for fabricating advanced thin films and coatings with enhanced properties and performance;
  • Advanced duplex procedures with combination of thermochemical surface modification with PVD or PACVD processes;
  • Novel hybrid deposition processes involving CVD/PVD to achieve application requirements;
  • Design and CVD/PVD fabrication of multilayer, nanostructured, multifunctional coatings;
  • Theory and experimentation on film formation, interfacial adhesion, surface preparation, contaminant control, and coating degradation mechanisms;
  • Advanced characterization and testing techniques to accelerate the discovery of new coating compositions and architectures;
  •  Computer modeling to predict coating properties, performance, and durability in simulated service environments.

(AlCrTiMoV)N high entropy nitride film was prepared on 17-4PH stainless steel substrate using cathodic arc evaporation (CAE). The composition, microstructure, and thermal stability were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). Mechanical properties such as hardness and Young’s modulus and coating performance against wear and erosion were also evaluated. The results show that the (AlCrTiMoV)N coating assumes a single-phased solid solution B1 FCC structure. It has excellent thermal stability and retains its structure with no decomposition observed up to a temperature of 1000 °C. The hardness and elastic modulus are measured as 21.3 GPa and 304 GPa, respectively. The coating contains some metallic droplets. As a potential protective coating, the (AlCrTiMoV)N coating has a lower wear rate but a higher erosion rate when compared to the TiN baseline coating. Full article

AlCrN coatings, which are characterized by high hardness and good wear resistance, are often used for drilling, milling, and punching tools. Therefore, the study of the behaviour of these coatings under cyclic impact loading is essential for their optimization. Our previous work has focused on the study of the composition and microstructure of AlCrN coatings prepared using a cathodic arc deposition system with a SCIL® controller that controls the average ion energy per deposited atom (Ed). Two sets of coatings were prepared in two different modes, with a metal target and with a poisoned target. The chemical compositions of the coatings were very similar regardless of their deposition conditions, but the structure and mechanical properties of the coatings depended strongly on Ed. The present work focused on the scratch adhesion and impact wear of these two sets of AlCrN coatings. The lifetimes of both sets of samples under repeated dynamic impacts were tested using a dynamic impact tester with a WC-Co ball. It was shown that the impact behaviour of the coatings prepared in the metallic regime does not depend on the deposition conditions. However, the impact behaviour of the coatings deposited in poisoned mode was improved by increasing Ed. Full article

The 316L stainless steels, often used in turbine blades for naval and marine applications, usually suffer from localized pitting corrosion after long exposure to chlorinated environments. The aluminum-zirconium coatings deposited by magnetron sputtering technique can be used to ensure cathodic protection for steels. In this work, we study the influence of atomic layer deposited (ALD) Al2O3, ZnO, and TiO2 thin films on the structural, mechanical, and electrochemical properties of Al-Zr (4 at.% Zr) magnetron sputtered coatings. The morphology, preferred orientation growth, mechanical properties, wettability, and corrosion resistance were investigated. The change in the sputtered Al-Zr morphology is mainly due to the insertion of the ALD layer. The Al-Zr layer deposited on ZnO and TiO2 layers presented a distinctive morphology. The agglomerate particles of AlZr/Al2O3/AlZr, AlZr/ZnO/AlZr and AlZr/TiO2/AlZr coatings exhibited a cauliflower shape. For ALD/PVD coatings, the insertion of an ALD oxide layer promoted the intensity of the peaks corresponding to the (111) crystallographic orientation. The nanoindentation measurements confirmed the enhancement in the mechanical properties, where the hardness increased by about 75%. The ALD oxide layers promoted the hydrophobicity of the coatings. The electrochemical characterization in a 3.5 wt.% NaCl solution also confirmed the role of the ALD oxides layers in delaying the pitting corrosion of the Al-Zr coating by widening the passive region and enhancing the protective efficiency of the passive film.
