| Abstract: | Bond coat NiCrAlYSi is fabricated firstly by plasma spraying method on the high-temperature alloys IC10,and ceramic layer Sc2O3-Y2O3-ZrO2is deposited on the bond coat. The coating samples are subjected to isothermal heatreatment at 1100℃, the fracture surface of different oxidation times is observed, a weight gain curve of sample is drawn, and the growth characteristics of TGO during high temperature is analyzed . |
