Special Issue Information

Dear Colleagues,

Thin layers technologies, in particular those based on physicochemical processes and hybrid deposition systems, are an important part of current studies in the field of surface engineering of coatings materials. In the case of functional materials, there is a growing need for novel interlayers and coatings that assure increased hardness, wear resistance, low friction coefficient, biocompatibility, etc. For instance, thin-layer deposition technologies, also provided in hybrid systems, allow to obtain of coatings on structural elements with complex shapes and simultaneously ensure good adhesion to the substrate, a homogeneous chemical composition, and precisely defined surface properties for the application. In this regard, technologies carried out in reduced pressure conditions involving physical phenomena and chemical reactions in plasma have excellent prospects, as well altogether with immersion methods. New, potential technologies are related to both the selection of the chemical and phase composition of thin coatings and the design of individual stages of the synthesis process, which lead to obtaining a novel material with a specific set of functional properties. Thus, importantly, intentional processes in hybrid systems can be useful to obtain layered materials for operating in the working conditions of a given structural element.

In view of the foregoing, we invite you to present your valuable research focused on the possibility to obtain functional coatings with the application of different deposition systems on metallic, polymeric, or ceramic substrates in the Special Issue of Materials entitled: “New Challenges of Coating Deposition Processes: Microstructure Evolution and Properties”. In particular, the topics of interest include, but are not limited to: (i) functional coatings, (ii) hybrid coatings, (iii) plasma processes, and (iv) microstructure evolution.

This article presents a comparative study of WC and CrC coatings deposited by the plasma-enhanced chemical vapor method using the hexacarbonyls of W and Cr as precursors. The measured thicknesses of the WC and CrC coatings are equal to ca. 1.5 µm. The WC coating consists of microcolumns with a conical end, with gaps between the microcolumns up to approximately 100 nm, and their structure is formed by nanoparticles in the shape of globules with a diameter of up to 10 nm. In the case of the CrC coating, a cauliflower structure with gaps ranging from 20 to 100 nm was achieved. The diameter of cauliflower grains is from 50 nm to 300 nm. The C content in the WC and CrC coating is 66.5 at.% and 75.5 at.%. The W content is 1.4 at.% and the Cr content in the CrC coating is 1.2 at.%. The hardness and Young’s modulus of the WC coating are equal to 9.2 ± 1.2 GPa 440.2 ± 14.2 GPa, respectively. The coefficients of friction and wear volume of the WC coating are equal to 0.7 and −1.6 × 106/+3.3 × 106 µm3, respectively. The hardness and Young’s modulus of the CrC coating are 7.5 ± 1.2 GPa and 280 ± 18.5 GPa, respectively. The coefficients of friction and wear volume of the CrC coating are 0.72 and −18.84 × 106/+0.35 × 106 µm3, respectively. Full article
