RISHigh-Temperature Solid Particle Erosion in a Melt-Infiltrated SiC/SiC Ceramic Matrix Composite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ceramic matrix composites are an enabling propulsion material system that offer weight benefits over current Ni-based superalloys, and have higher temperature capabilities that can reduce cooling requirements. Incorporating ...
A Dynamic Testing Approach for Particulate Erosion–Corrosion for Gas Turbine Coatings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Particle interactions in engines can be complex phenomena leading to degradation of thermal (TBCs) and environmental barrier coatings (EBCs) meant to protect engine components. Ingestion of particles into the engine can ...
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 ...
Expanding 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 ...
Multi-Lead Direct Current Potential Drop Method for In Situ Health Monitoring of Ceramic Matrix Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The method of direct current potential drop (DCPD) can be utilized as an effective and convenient approach for in situ damage detection, and as a nondestructive evaluation technique. We present the results from use of a ...
Life-Limiting Behavior of an Oxide/Oxide Ceramic Matrix Composite at Elevated Temperature Subject to Foreign Object Damage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The life-limiting behavior of an N720/alumina oxide/oxide ceramic matrix composite (CMC) was assessed in tension in air at 1200 °C for unimpacted and impacted specimens. CMC targets were subjected to ballistic impact at ...
An Investigation of the End-Notched Flexure and End-Loaded Split Tests Applied to the Mode II Interlaminar Fracture of a SiC/SiC Ceramic Matrix Composite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Delamination is a common failure mode observed in ceramic matrix composites (CMCs) and occurs as a result of applied interlaminar tensile and shear stresses exceeding the interlaminar strength. As CMCs are further implemented ...
