Notes:
Thermal barrier coating (TBC) was carried out on Ni based super-alloy specimens, and edgeindent tests were carried out at 1073K under different displacement rate. In addition, the specimens wereheated and held at 1273K for long time, and the edge-indent tests of the specimens were performed bothat 1273K and at room temperature. The results showed that the delamination load Pd and thedelamination energy Ed measured at 1073K after short time holding were larger than those measured atroom temperature, and the Pd and Ed slightly decreased with increasing displacement rate at 1073K whilethey slightly increased at 293K. The Pd and Ed at 1273K increased with increasing holding time andreached a maximum at 1400ks. With further increase in holding time, the Pd and Ed largely decreased.The Pd and Ed measured at 1273K were smaller than those at room temperature
