| Outline of Final Research Achievements |
We attempted to develop thick ceramic film with structural duration property in 30000℃/s high heat-shock environment such as thermal barrier coatings(TBC). The heat-shock properties of metal-oxide films synthesized from a metal-EDTA complex were investigated. Y2O3 films were synthesized on stainless-steel (SUS) substrate from Y-EDTA through the combustion of H2-O2 gas. A cyclic heat-shock test was conducted on the fabricated Y2O3 films through exposure to the H2-O2 flame. Although the number of cross-sectional cracks, crack lengths, and cracks per unit area was increased by the heat shock, delaminations were not observed in the Y2O3 films. Same phenomena were observed in Er2O3 on SUS substrate in second year. Furthermore, we accomplished to deposit metal oxide with high heat-shock property film on aluminum alloy. These results show that the metal oxide films with chelate materials have high thermal-shock resistance and are promising candidate for as TBC.
