Coatings for Use at High Temperatures

Technical Symposia: A | B | C | D | E | F | G | H
Topical Symposia: TS1 | TS2 | TS3 | TS4
| TS5

Symposium Chairs

Vincent Maurel, Mines - ParisTech, France,
Prabhakar Mohan, Solar Turbines Inc., USA,
Francisco Javier Perez Trujillo, Universidad Complutense de Madrid, Spain,

Symposium A addresses coatings and surface modifications whose primary purpose is to sustain system performance under high-temperature and harsh thermochemical environments. Topics of interest include high-temperature aging, stress, corrosion (e.g., oxidation, sulfidation, carburization, and water-accelerated degradation), catalytic and physical fouling (e.g., coking, ash fouling, and slagging), and wear (e.g., abrasion, erosion, and impact), characterization and mechanistic understanding of high-temperature degradation and mitigation technologies. Typical applications span gas/steam turbines, coal, geothermal, biomass energy conversion, and chemical/petrochemical processes.


A1. Coatings to Resist High-temperature Oxidation, Corrosion, and Fouling

Session Chairs

Vladislav Kolarik, Fraunhofer Institute for Chemical Technology ICT, Germany
Shigenari Hayashi, Hokkaido University, Japan,
Sebastien Dryepondt, Oak Ridge National Laboratory, USA,

Session A1 spans all aspects of design, processing, and performance of coatings to resist high-temperature oxidation, corrosion, and fouling. Topics include composition and process optimization, effects of applied stress, characterization of coatings and reaction products, new processing methods, and modeling of fabrication and degradation processes (e.g., coating-substrate interdiffusion, thermal cycling, water-accelerated degradation, and phase and microstructural stability). Applications include gas and steam turbomachinery, diesel engines, petrochemical and gasification plants, geothermal energy, waste incinerators, boilers and metal-forming industries. Contributions addressing issues as well as solutions are encouraged, with focus on coatings and surface modification.

A2. Thermal and Environmental Barrier Coatings

Session Chairs

Lars-Gunnar Johansson, Chalmers University of Technology, Sweden,
Kang Lee, NASA Glenn Research Center, USA,
Pantcho Stoyanov, Pratt & Whitney, USA,

Session A2 focuses on the design, development, synthesis, and applications of thermal and environmental barrier coatings for gas turbines and other high-temperature applications. Topics include process understanding and novel processing methods, characterization of coating microstructure, properties (thermal, optical, mechanical, and chemical), testing methods (destructive and nondestructive), structure-property relationships, residual stresses, aging phenomena, substrate/coating system effects, and failure mechanisms, including erosion, abrasion, and impact. These topics can be addressed for experimental and/or modeling development.

Invited Speakers

“Corrosion Degradation of High Temperature Coatings: Similarities and Differences for Marine and Aero-Turbine Applications”

Lisa Pin, Safran Ceramics, France
“Enhanced EBC Development and Behavior Analysis for High Temperature CMC Components”


A3. Materials and Coatings for Solar Power Concentration Plants

Session Chairs

Gustavo Garcia Martin, REP-Energy Solutions, Spain,
Vladislav Kolarik, Fraunhofer Institute for Chemical Technology ICT, Germany

Session A3 focuses on materials and coatings for emerging concentrating solar power (CSP) plants. The two concepts of central tower and parabolic plants with HTF (heat transfer fluids) and STF (storage transfer fluids) will be addressed in this session. Those plants need to work at higher temperatures than conventional ones and require protective systems, such as coatings, compatible with fluids under corrosive environment to enhance the performance, efficiency and durability of the plant. The session addresses, for these new and disruptive technology concepts, any part of the plant, considering key points in the design and O&M, such as: absorbers, reflectors, piping, energy storage tanks and components. On the other hand, new plants will be operated with thermal storage with molten salts to allow the plant to operate without sunlight. All materials design related with molten salts applications will be considered as a key issue in this session, as well as new high temperature hybridization technologies. Coating technologies, properties, typical degradation mechanisms, chemical and physical interactions as well as concepts for enhancing the efficiency and lifetime will be discussed in this new session.
