Abstract

NbSi₂/SiO₂-Nb₂O₅/HfSi₂-HfO₂ multilayer ceramic coating containing Hf-rich out layers is designed and prepared on dense NbSi₂ surface via pack cementation and subsequent liquid plasma-assisted particle deposition and sintering of HfSi₂ particles to enhance oxidation resistance. The obtained ceramic layer contains the SiO₂-Nb₂O₅ intermediate bonding-layer and the oxygen barrier outer-layer of HfSi₂-HfO₂. The mass gain of NbSi₂/SiO₂-Nb₂O₅/HfSi₂-HfO₂ coating (5.583 mg/cm²) is only 40 % compared to the NbSi₂ coating (13.702 mg/cm²) after 100 h at 1200 °C. The HfO₂ and HfSiO₄ phases formed at high-temperatures are anchored in SiO₂ scale, enhancing the structural stability of ceramic phase and blocking oxygen penetration. Namely, the “Hf nail” fixed on SiO₂ scale effectively inhibits Nb-oxide growth and crack initiation.
