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.
