Krishnasamy, J. (author), Ponnusami, Sathiskumar A. (author), Turteltaub, S.R. (author), van der Zwaag, S. (author)The thermal cyclic behavior of self-healing thermal barrier coatings (SH-TBC) is analyzed numerically to develop a lifetime prediction model. Representative microstructures are studied adopting a unit cell based multiscale modeling approach along with a simplified evolution model for the thermally-grown oxide layer (TGO) to study the...journal article 2021

(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

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
