CSP - Thermal Barrier Coatings V Conference
Abstract
The proposed conference will be fifth in series of conferences sponsored by ECI at Irsee, Germany onThermal Barrier Coatings (TBC). Thermal Barrier Coating (TBC) Systems continue to be a key materialstechnology that offers great benefit to the operation of gas turbine aircraft engines, gas turbineshipboard engines, land base industrial gas turbine engines, and recently diesel reciprocatingengines. The technology associated with TBC has progressed steadily since the introduction of thesescoatings over fifty years ago. It is note - worthy that research in thermal barrier coatings hasaccelerated greatly in the past twenty years and that this research has resulted in the commercialand military use of new bond coats, low conductivity coatings, coatings that resist degradationinduced by environmental deposits ingested into the engine.Current research includes development of prime-reliant TBCs, coatings capable to operate at highertemperatures, new reliable and cost-effective manufacturing routes especially in the area of thermalspray, and recently TBCs that will resist reaction with deposits such as CMAS or volcanic ash. Anemerging area of research is combined thermal and environmental barrier coatings that protectceramic matrix composites, new silicide-based materials, titanium, and cobalt-based single crystalalloys where the coatings are key for successful introduction of the materials into application.Thermal barrier coating systems are now key elements in the design of new and advanced enginesand are enabling many new designs with improved efficiencies and higher thrusts. Extensive researchand development of TBC is being carried out in every major industrialized country by industry,academia, and national institutions and laboratories.Very successful TBC conferences were sponsored by ECI at Kloster Irsee, Germany during in 2003,2007, 2011, and 2014. Over 400 researchers and practitioners in total attended these conferences.Although energy transition lead in several countries to reduced research efforts for large stationarygas turbines, research activity has continued to be strong especially in the aero engine sector and thesuccessful implementation of new and advanced coating systems has been achieved. Severaltechnologies that were in the developmental phase and reported on at previous ECI TBC Conferencesare now being deployed and can be discussed. Also since the last conference, research activities inTBCs are still increasing in different parts of the world as Eastern Asia and there especially China. It isthus timely to have a sequel to the prior Irsee meetings to bring together scientist, engineers,professors, and students to report and discuss recent progress in TBC development and use, anddefine future development activities and directions. Recent workshops, such as ICACC and ICMCTFthat also cover this technology have been consistently well-attended and dynamic in nature. Inaddition, workshops on processing related issues as suspension plasma spraying with a special focuson TBCs are receiving increasing interest. Thermal barrier coatings are complex, multi-layered, andmulti-material systems with many variants related to composition, processing and microstructure.Further understanding of the science and behavior of these materials that will result in the successfuladvancement of the technology requires a truly multidisciplinary approach. Here also the progressmade within high resolution and scale bridging characterization tools can play a major role. The fieldhas attracted a diverse group of scientists all over the world and combines ceramics, metals, metalceramicinterfaces, processing, mechanisms of TBC performance and degradation includingenvironmental attack and oxidation, thermal transport, diffusion and applications in a variety ofaggressive environments.Research on thermal and environmental barrier coatings allows to operate components at aconsiderably higher temperature than their materials capability would allow, there
