(author)Recently MoSi<sub>2</sub> sacrificial particles embedded in yttria partially stabilized zirconia (YPSZ)have been proposed as attractive healing agents to realize significant extension of the lifetime of the thermally loaded structures. Upon local fracture of the YPSZ, the embedded healing particles in the path and in the vicinity of the crack...journal article 2019

(author)A successful sol-gel process to encapsulate molybdenum di-silicide MoSi<sub>2</sub> particles with a closed and thermally stable Al<sub>2</sub>O<sub>3</sub> layer using aluminium tri-sec-butoxide as a precursor is presented. The processing conditions such as precursor selection and temperature were optimized through analysing the interaction...journal article 2018

(author), van der Zwaag, S. (author), Withers, Philip J. (author), Xiao, Ping (author)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...journal article 2018

Nozahic, Franck (author), Estournès, Claude (author), Carabat, A.L. (author), Sloof, W.G. (author), van der Zwaag, S. (author), Monceau, Daniel (author)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<...journal article 2018

Carabat, A.L. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)Easy crack propagation in oxide ceramic coatings limits their application in high temperature environment (e.g. such as engines and gas turbine components) [1]. In order to overcome this problem, incorporation of sacrificial particles into an oxide ceramic coating may be a viable option. Particles of silicon compounds, such as: Si3N4, SiC, MoSi2...conference paper 2013
