Special Issue Information

Dear Colleagues,

This Special Issue of Coatings, entitled “Advances in Thermal Spray Coatings: Technologies and Applications”, is open for submissions. We would like to invite you to submit your research to this Issue.

Thermal spraying is an emerging coating development process that allows the use of a wide range of materials, including metals, cermets, ceramics and polymers, in the form of powders, suspension/liquid precursors, rods, or wire. The modification or variation of the feeding techniques, as well as the optimization of the spraying parameters, make the coatings applicable in different fields (i.e., wear, erosion, cavitation, corrosion, abrasion, or heat) depending on the desired conditions. Its application can be used to extend the life of new components or, using proven techniques, to repair and rebuild worn or damaged components.

In the Special Issue, we would like to hear about the latest developments and achievements in the field of thermal spraying.

Thus, we cordially invite scientists and academics from all over the world to submit original research papers and review articles on thermal spraying, its latest developments and applications, as well as coating properties and performance.

Topics of interest include, but are not limited to:

  • New processes in the development of new coatings
  • Coating properties and performance
  • Feedstock material developments
  • Friction, wear, and corrosion
  • New coating materials
  • Functional coatings

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). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This work represents a preliminary study of atmospheric plasma-sprayed (APS) Yttria-Stabilized Zirconia (YSZ)-based thermal barrier coatings (TBCs) deposited on forged and additive manufactured (AM) HAYNES®282® (H282) superalloy substrates. The effect of different feedstock morphologies and spray gun designs with radial and axial injection on APS-deposited YSZ layer characteristics such as microstructure, porosity content, roughness, etc., has been investigated. The performance of TBCs in terms of thermal cycling fatigue (TCF) lifetime and erosion behaviour were also comprehensively investigated. In view of the high surface roughness of as-built AM surfaces compared to forged substrates, two different types of NiCoCrAlY bond coats were examined: one involved high-velocity air fuel (HVAF) spraying of a finer powder, and the other involved APS deposition of a coarser feedstock. Despite the process and feedstock differences, the above two routes yielded comparable bond coat surface roughness on both types of substrates. Variation in porosity level in the APS topcoat was observed when deposited using different YSZ feedstock powders employing axial or radial injection. However, the resultant TBCs on AM-derived substrates were observed to possess similar microstructures and functional properties as TBCs deposited on reference (forged) substrates for any given YSZ deposition process and feedstock.
