Spark plasma sintering (SPS) is a highly efficient method for the preparation of a/β-SiAlONceramics. However, the rapid preparation of large-scale a/β-SiAlON ceramic components withreliable mechanical properties is diffcult via SPS due to their near-insulating properties. In thisstudy, high-performa

Rare-earth aluminates (REAlO;) are potential thermal barrier coating (TBC) materials, but therelatively high thermal conductivity (k,, ~13.6 Wm'K') and low fracture toughness (Kic, ~1.9MPa·m') limit their application. This work proposed a strategy to improve their propertiesthrough the synergistic e

Silicon nitride (Si3N4) with excellent mechanical properties and chemical stability, has been widely used in many fields. However, wear failure is often the cause of the short life of Si3N4 devices at high temperatures, thereby the wear resistance of Si3N4 ceramics still needs to be further improved.

Ultrashort-pulse lasers (USPLs) are used in the machining of zirconia ceramics (ZrO2) because of their extremely high peak intensities. However, highly efficient and high precision microprocessing of ZrO2 remains challenging.

Thanks to its advantages of high efficiency and near-net shaping, laser directed energy deposition (LDED) is rapidly becoming a remarkable preparation technology for high-purity ceramics.
