We investigated the heat-shock properties of metal-oxide films synthesized from a metalethylenediamine tetraacetic acid (EDTA) complex. Y2O3 films were synthesized on a stainless-steel (SUS) substrate from EDTAûYûH 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. The existence of Y2O3 crystals was confirmed. Although the number of cracks, crack lengths, and cracks per unit area were increased by the heat shock, delaminations were not observed in the Y2O3 films. The results show that the prepared Y2O3 films have high thermal-shock resistance and are suitable for use as thermal barrier coatings. |
