Special Issue Information

Dear Colleagues,

A new Special Issue, entitled “Thermal Barrier Coatings: Design, Characterization, Failure Analysis, and Applications”, has been launched. This Special Issue solicits contributions related to the latest experimental and theoretical developments in the design, characterization, failure analysis, and applications of thermal barrier coatings.

Thermal barrier coatings (TBCs) are often used as high-temperature-resistant protective coatings for the thermal protection and corrosion protection of aero engines. However, degradation occurs both in thermal and mechanical performances during service. Thus, understanding the degradation and failure mechanisms of TBCs is significant in the assessment and further enhancement of the durability and reliability of TBCs. This Special Issue aims to bring together original research articles and topical reviews with a focus on thermal barrier coatings for high-temperature applications.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Mechanical properties of ceramic coatings;
  • Corrosion behaviour of TBCs;
  • Failure analysis;
  • High-temperature corrosion and high-temperature protection;
  • Theoretical and computational modelling;
  •  The preparation and application of TBCs;
  • Non-destructive testing technology.

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.

To tackle the ever-increasing operating temperature of aero-engines, a La2Ce2O7 (LCO)/yttria partially stabilized zirconia (YSZ) double-layer thermal barrier coating (TBC) was investigated. The LCO/YSZ double-layer samples were annealed with volcanic ash (VA) at 1250 °C to assess their stability in comparison with that of standard single-layer YSZ. The findings showed that the double-layer system exhibited greater resistance to VA damage than the single-layer YSZ coating. The corrosion mechanism was characterized by a rapid crystallization reaction between LCO and VA, where the kinetics of the solution’s reprecipitation reaction outpaced the penetration rate into the coating’s open pores.
