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.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project was to explore and develop a novel class of nanoscale reinforced ceramic coatings for high temperature (600-1000 C) corrosion protection of metallic components in a coal-fired environment. It was focused on developing coatings that are easy to process and low cost. The approach was to use high-yield preceramic polymers loaded with nano-size fillers. The complex interplay of the particles in the polymer, their role in controlling shrinkage and phase evolution during thermal treatment, resulting densification and microstructural evolution, mechanical properties and effectiveness as corrosion protection coatings were investigated. Fe-and Ni-based alloys currently used in coal-fired environments do not possess the requisite corrosion and oxidation resistance for next generation of advanced power systems. One example of this is the power plants that use ultra supercritical steam as the working fluid. The increase in thermal efficiency of the plant and decrease in pollutant emissions are only possible by changing the properties of steam from supercritical to ultra supercritical. However, the conditions, 650 C and 34.5 MPa, are too severe and result in higher rate of corrosion due to higher metal temperatures. Coating the metallic components with ceramics that are resistant to corrosion, oxidation and erosion, is an economical and immediate solution to this problem. Good high temperature corrosion protection ceramic coatings for metallic structures must have a set of properties that are difficult to achieve using established processing techniques. The required properties include ease of coating complex shapes, low processing temperatures, thermal expansion match with metallic structures and good mechanical and chemical properties. Nanoscale reinforced composite coatings in which the matrix is derived from preceramic polymers have the potential to meet these requirements. The research was focused on developing suitable material systems and processing techniques for these coatings. In addition, we investigated the effect of microstructure on the mechanical properties and oxidation protection ability of the coatings. Coatings were developed to provide oxidation protection to both ferritic and austentic alloys and Ni-based alloys. The coatings that we developed are based on low viscosity pre-ceramic polymers. Thus they can be easily applied to any shape by using a variety of techniques including dip-coating, spray-coating and painting. The polymers are loaded with a variety of nanoparticles. The nanoparticles have two primary roles: control of the final composition and phases (and hence the properties); and control of the shrinkage during thermal decomposition of the polymer. Thus the selection of the nanoparticles was the most critical aspect of this project. Based on the results of the processing studies, the performance of selected coatings in oxidizing conditions (both static and cyclic) was investigated.
Book Synopsis Advancements in Fiber, Interface, and Matrix Materials for Ceramic Matrix Composites by : Rebecca E. Gottlieb

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical Vapor Deposition (CVD) was used to deposit a variety of carbide, boride, and nitride interfacial coatings on substrates including silicon carbide based ceramic fibers for use in fabrication of components in Ceramic Matrix Composites (CMCs). Experiments were designed to correlate coating thickness and time required for these coating depositions and the materials fabricated in these experiments were used in various other experimental designs in this work. Coatings were characterized for their thickness and morphology, as well as to identify the phases present in the materials. A polycarbosilane pre-ceramic polymer was developed using a modified in-situ Grignard reaction with chlorinated silane precursors. This polymer was designed for use as both a precursor to silicon carbide ceramic fibers and for the ceramic matrix material in CMCs fabricated using Polymer Impregnation Pyrolysis (PIP). The polymer was characterized using Fourier Transform Infrared (FT-IR) spectroscopy and 1 H Nuclear Magnetic Resonance (NMR) to identify functional groups and to propose polymer structure, and Thermogravimetric Analysis coupled with Mass Spectrometry (TG-MS)was used to propose a mechanism for ceramic formation. The pyrolyzed ceramic was characterized using X-Ray Diffraction (XRD) to determine crystalline phases present, Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Spectroscopy (EDS) to examine grain morphology and elemental distribution. A second pre-ceramic polymer was designed to incorporate titanium and boron into a commercially available polymer (Starfire® SMP-10) for the intention of improving select properties for use in CMCs as both a fiber precursor and as a matrix material. The polymer was designed to form silicon carbide and titanium diboride upon pyrolysis in a two-step process. Titanium was first incorporated into the polymer, followed by a heat-treatment in boron trichloride to boronize the titanium. Both the as-received polymer and the modified polymer were characterized using TG-MS to determine the ceramic yield and mechanism of ceramic formation. Heat treatment studies were performed using XRD to determine the optimum temperature range for boron incorporation during the heat treatment. The ceramic was characterized using SEM and EDS to examine the grain growth inhibition provided by the titanium diboride, as well as to determine elemental distribution in the ceramics. CMCs were fabricated from both the commercially available polymer and the modified polymer and the composites were analyzed for the ultimate Flexural Stress measured before mechanical failure occurred. Cobalt metal was deposited on a variety of substrates including ceramic fiber and then coated with CVD silicon dioxide and Chemical Vapor Inf iltration (CVI) silicon carbide protective coatings for use in a magnetic ceramic matrix composite. The protective coatings were designed to help increase oxidation resistance so the composite would retain magnetic properties at elevated temperatures under oxidizing conditions. The material was characterized using XRD to determine crystalline phases present, and SEM and EDS were used to examine the coating morphology, adhesion, and elemental distribution in the composite. Superconducting Quantum Interference Device (SQUID) was used to determine the magnetic properties of the material during coating application and oxidation resistance studies. Tensile testing was used to to determine the ultimate tensile strength and the effect on coating application and oxidation on the strength of the composite both with and without the oxidation resistive coatings.

Book excerpt: The global increase in air travel will require commercial vehicles to be more efficient than ever before. Advanced engine hot section materials are a key technology required to keep fuel consumption and emission to a minimum in next-generation gas turbines. Ceramic matrix composites (CMCs) are the most promising material to revolutionize gas turbine hot section materials technology because of their excellent high‐temperature properties. Rapid surface recession due to volatilization by water vapor is the Achilles heel of CMCs. Environmental barrier coatings (EBCs) is an enabling technology for CMCs, since it protects CMCs from water vapor. The first CMC component entered into service in 2016 in a commercial engine, and more CMC components are scheduled to follow within the next few years. One of the most difficult challenges to CMC components is EBC durability, because failure of EBC leads to a rapid reduction in CMC component life. Key contributors to EBC failure include recession, oxidation, degradation by calcium‐aluminum‐magnesium silicates (CMAS) deposits, thermal and thermo‐mechanical strains, particle erosion, and foreign object damage (FOD). Novel EBC chemistries, creative EBC designs, and robust processes are required to meet EBC durability challenges. Engine-relevant testing, characterization, and lifing methods need to be developed to improve EBC reliability. The aim of this Special Issue is to present recent advances in EBC technology to address these issues. In particular, topics of interest include but are not limited to the following: • Novel EBC chemistries and designs; • Processing including plasma spray, suspension plasma spray, solution precursor plasma spray, slurry process, PS-PVD, EB-PVD, and CVD; • Testing, characterization, and modeling; • Lifing.
