Special Issue Information

Dear Colleagues,

To respond to the current high technological demand, materials play a preponderant role in the life cycle of innovative products. The deposition of thin films to assign specific characteristics and, thus, make products more competitive has attracted a great deal of attention from researchers, these studies focusing on improving the tribological behavior, optical enhancement, wear resistance, structural strengthening, visual/aesthetic enhancement, and many other fields with a wide range of applications.

Improving the characteristics of materials, e.g., adhesion to the substrate, wear resistance, etc., as well as coating techniques to offer combinations normally not possible in a single material, are highly sought-after topics by researchers, nanostructured coatings deserving special interest, with their characterization being a hot topic.

This Special Issue aims to compile topics related to coating processes, ways to optimize the coating process, and seeking relationships with improvements in industrial requirements depending on the product and market demand.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Coatings is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs).

The excellent adhesion strength between the substrate and coating in the field of cemented carbide-coated tools is the crux of ensuring the durability of coated tools. The TiN coating is often used as a bonding layer to improve the bonding strength between the substrate and outer coating. Insights into detailed information on the interfacial properties between substrate and coating are essential for developing coating structures with optimal adhesion properties. Therefore, first-principles calculations were used to investigate the anisotropy of the elastic characteristics of WC and TiN as well as the bonding mechanism at the interface. The findings demonstrate that WC and TiN bulks have different symmetries in their anisotropy of elastic characteristics. WC(0001) and TiN(111) slabs can be well-lattice matched thanks to the low lattice mismatch ratio (2.7%). The HCP stacking mode has larger bonding energy than the OT and hole stacking modes in the interface structure with identical terminating atoms. The C-HCP-Ti interface forms covalent and ionic bonds, which is thermodynamically stable (γ = −1.127 J/m2) and has the highest bonding strength (Wad = 8.899 J/m2) among all interface structures. The results of this study provide a practical perspective for improving the mechanical properties of cemented carbide-coated tools. Full article
