This book was released on 2018-06-19 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Issues and design requirements for the environmental barrier coating (EBC)/thermal barrier coating (TBC) life that are general and those specific to the NASA Ultra-Efficient Engine Technology (UEET) development program have been described. The current state and trend of the research, methods in vogue related to the failure analysis, and long-term behavior and life prediction of EBCITBC systems are reported. Also, the perceived failure mechanisms, variables, and related uncertainties governing the EBCITBC system life are summarized. A combined heat transfer and structural analysis approach based on the oxidation kinetics using the Arrhenius theory is proposed to develop a life prediction model for the EBC/TBC systems. Stochastic process-based reliability approach that includes the physical variables such as gas pressure, temperature, velocity, moisture content, crack density, oxygen content, etc., is suggested. Benefits of the reliability-based approach are also discussed in the report. Shah, Ashwin R. and Brewer, David N. and Murthy, Pappu L. N.

This book was released on 2017-06-12 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global population growth and tremendous economic development has brought us to the crossroads of long-term sustainability and risk of irreversible changes in the ecosystem. Energy efficient and ecofriendly technologies and systems are critically needed for further growth and sustainable development. While ceramic matrix composites were originally developed to overcome problems associated with the brittle nature of monolithic ceramics, today the composites can be tailored for customized purposes and offer energy efficient and ecofriendly applications, including aerospace, ground transportation, and power generation systems. The 9th International Conference on High Temperature Ceramic Matrix Composites (HTCMC 9) was held in Toronto, Canada, June 26-30, 2016 to discuss challenges and opportunities in manufacturing, commercialization, and applications for these important material systems. The Global Forum on Advanced Materials and Technologies for Sustainable Development (GFMAT 2016) was held in conjunction with HTCMC 9 to address key issues, challenges, and opportunities in a variety of advanced materials and technologies that are critically needed for sustainable societal development. This Ceramic Transactions volume contains a collection of peer reviewed papers from the 16 below symposia that were submitted from these two conferences Design and Development of Advanced Ceramic Fibers, Interfaces, and Interphases in Composites- A Symposium in Honor of Professor Roger Naslain Innovative Design, Advanced Processing, and Manufacturing Technologies Materials for Extreme Environments: Ultrahigh Temperature Ceramics (UHTCs) and Nano-laminated Ternary Carbides and Nitrides (MAX Phases) Polymer Derived Ceramics and Composites Advanced Thermal and Environmental Barrier Coatings: Processing, Properties, and Applications Thermomechanical Behavior and Performance of Composites Ceramic Integration and Additive Manufacturing Technologies Component Testing and Evaluation of Composites CMC Applications in Transportation and Industrial Systems Powder Processing Innovation and Technologies for Advanced Materials and Sustainable Development Novel, Green, and Strategic Processing and Manufacturing Technologies Ceramics for Sustainable Infrastructure: Geopolymers and Sustainable Composites Advanced Materials, Technologies, and Devices for Electro-optical and Medical Applications Porous Ceramics for Advanced Applications Through Innovative Processing Multifunctional Coatings for Sustainable Energy and Environmental Applications
