Bei, G. (author), van der Zwaag, S. (author), Kota, Sanklap (author), Barsoum, Michel W. (author), Sloof, W.G. (author)The ultra-high temperature ablation of a polycrystalline, fully dense, predominantly single phase MoAlB ceramic discs under an oxyacetylene flame is examined. The linear ablation rate decreases from 1.3 μm/s during the first 30 s to - 0.7 μm/s after 60 s when the surface temperature reached about 2050 °C (with a flame temperature around 3000 °C)...journal article 2019

Boatemaa, L. (author), van der Zwaag, S. (author), Sloof, W.G. (author)This work explores the possibility of using embedded micron-sized Ti particles to heal surface cracks in alumina and to unravel the evolution of the crack filling process in case of pure solid-state oxidation reactions. The oxidation kinetics of the Ti particles is studied and the results are applied in a simple model for crack-gap filling....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
