Special Issue Information
Dear Colleagues,
Advanced thermal barrier coatings (TBCs) are widely employed as critical thermal protection for modern gas turbines and aero-engines, effectively reducing the superalloy substrate temperature of turbine blades or vanes and improving their structure reliability at elevated temperatures. Due to operating in the aggressive environment and suffering the thermal misfit stress combined with the mechanical load transmitted by the substrate, the performance of TBCs is prone to gradually degrade caused by metallic bond coat oxidation, ceramic sintering, corrosion/erosion, etc. The failure of TBCs, including corrosion, fracture, and spalling during in-service, can cause the overheating of turbine blades, probably resulting in significant safety accidents and economic losses. For the advanced TBCs, analysis, modeling, and experiment on durability and reliability can make contributions to promote the performance and improve the structural reliability of gas turbines and aero-engines.
The scope of this Special Issue will serve as a forum for papers in the following concepts:
- Recent developments on the durability and reliability of TBCs
- Modeling and simulations of properties, performance, durability and reliability of TBCs
- Gradual degradation of TBCs through corrosion, errosion, sintering, and oxidation
- Experiments on corrsion, fracture and failure of TBCs
- Improvement and optimization of materials and processes
- Novel structures and materials of TBCs including Graphene etc.

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.
