Ceramic Coating


We investigated the initiation and propagation of cracks in ceramic coating in term of multi-scale observations: in situ XAFS, XAFS-CT (to be installed in 2016 FY)

Multi-scale complementary approaches for finding “trigger sites” of the degradation mechanism

Chemical state mapping of heterogeneous reduction of iron ore sinter.

June 21, 2017

Degradation of EBC progresses heterogeneously during heat cycles. Observation of the heterogeneous reaction, especially change of chemical states is of great importance. We developed the chemical state mapping using XANES, and applied it to a model case: heterogeneous reduction of iron oxides.
