Dear Colleagues,

For decades, thermal spraying (TS) has widely been considered an optimal choice for the application of coatings with the goal of protecting materials from corrosion, oxidation, and wear degradation. The variety of TS techniques that exist, ranging from the conventional deposition techniques, which require both kinetic and thermal energy (high particle velocity and temperature), to the newest technique (cold gas spray) in which mainly kinetic energy is used for coating formation, allows the deposition of a huge variety of materials for modifying the functionality of materials’ surfaces with this protective purpose. Nowadays, TS processes are still of great interest for the development of smart coatings with new protective functionalities (e.g., self-healing, self-lubricated, and superhydrophobic properties), and for this it is no doubt true that the newest TS techniques (CGS, suspension plasma spray) will make a key contribution to the future of TS technology. Consequently, this Special Issue aims to investigate and address the future challenges of thermal spraying in terms of improving coating functionalities and developing new thermal spray processes in different advanced industrial sectors. Original research articles as well as review papers on the state of the art of the thermal spraying for surface protection purposes are welcome.

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. Materials is an international peer-reviewed open access semimonthly 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.
