RISExpanding the Capability of a Legacy Combustion Flame Tube to Test High-Temperature Engine Materials in Relevant Environments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: New materials and component designs are needed to advance gas turbine engine technology and provide the performance and efficiency needs for future applications. In order to advance these materials, testing in combustion ...
Design of an Environmental Barrier Coating Bond Strength Test Coupon
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The bond strength of an environmental barrier coating (EBC) to a substrate such as a silicon carbide fiber/silicon carbide matrix (SiC/SiC) ceramic matrix composite (CMC) is a function of coating application parameters, ...
Environmental Barrier Coating Oxidation and Adhesion Strength
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Plasma spray-physical vapor deposition (PS-PVD) environmental barrier coatings (EBCs) of Yb2Si2O7 were deposited on SiC and exposed in a steam environment (90% H2O/O2) at 1426 °C to form a thermally grown oxide (TGO) layer ...
Thermally Grown Oxide Stress in PS-PVD and EB-PVD Thermal Barrier Coatings Observed at Various Lifetimes Via Synchrotron X-ray Diffraction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current standard application method for thermal barrier coatings (TBCs) on turbine blades for jet engines is electron-beam physical vapor deposition (EB-PVD) due to its high strain tolerance and low thermal conductivity. ...
