RISKey Durability Issues With Mullite-Based Environmental Barrier Coatings for Si-Based Ceramics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Plasma-sprayed mullite (3Al2O3⋅2SiO2) and mullite/yttria-stabilized-zirconia (YSZ) dual layer coatings have been developed to protect silicon-based ceramics from environmental attack. Mullite-based ...
Microstructure and Wear Behavior of Nano-TiB2p/2024Al Matrix Composites Fabricated by Laser Direct Energy Deposition With Powder Feeding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this study is to investigate the effect of TiB2 content on the microstructure and wear behavior of nano-TiB2p/2024Al composites fabricated by laser direct energy deposition (L-DED). The dry sliding friction ...
