Special Issue Information
Dear Colleagues,
This Special Issue aims to provide a platform for the latest advancements in thermal and environmental barrier coatings, highlighting innovative solutions to current challenges facing next-generation coating protection systems.
Thermal and environmental barrier coatings (TBCs/EBCs) have been enabling technologies in the deployment of nickel-based superalloy and SiC-based ceramic matrix composite components in the hot section of gas turbine engines. Over 30 years of coating development have enabled the achievement of higher operating temperatures, although challenges remain to further increase inlet temperatures and improve engine efficiencies. These coatings face a multitude of damage mechanisms, including combustion species-based corrosion and oxidation, corrosion from molten deposits of calcium-magnesium aluminosilicate (CMAS) particulates, thermal cyclic stresses, solid particle erosion, and foreign object damage. All these damage mechanisms occur simultaneously in gas turbines, and therefore, strong interactions between various degradation modes are expected. Additionally, higher operating temperatures (>1400 °C) will exacerbate these degradation modes and surpass the temperature capability of current state-of-the-art (SOA) coating systems.
Future TBCs/EBCs must have substantially higher temperature durability, which necessitates the development of combined degradation mode testing to accurately assess coating lifetimes in relevant environments. Submissions can include novel and multifunctional coating compositions that push the temperature capability above SOA systems (>1400 °C), microstructural tailoring to improve environmental durability, developments and results in synergistic testing of coating systems, as well as advances in protective coatings for refractory alloys and other CMCs (carbides, borides, Al2O3-based CMCs, etc.). We look forward to contributing to shaping the future of protective coatings in this Special Issue.

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.
