Yttria – partially stabilised zirconia (YPSZ) MoSi<sub>2</sub> composites have been designed to prolong the lifetime of the matrix by self – healing cracks during thermal cycling. The healing reaction at high temperatures is based on the decomposition of MoSi<sub>2</sub>, leading to a volumetrically expanding reaction product, which seals the...

The present paper focuses on the Spark Plasma Sintering (SPS) manufacturing of a new type of self-healing thermal barrier coating (TBC) and a study of its thermal cycling behaviour. The ceramic coating consists on an Yttria Partially Stabilized Zirconia (YPSZ) matrix into which healing agents made of MoSi<sub>2</sub>-Al<sub>2</sub>O<sub>3<...
