摘要	Thermal barrier coatings (TBCs) were obtained using a detonation gun (D-gun) spraying technique on a Ni-base superalloy, M38G. The thermal conductivity of freestanding YSZ coatings and the thermal shock behaviors of TBCs system were studied. The results showed that the D-gun sprayed TBC had a very low thermal conductivity of 1.0-1.4 W/m K, close to that of the plasma sprayed YSZ coatings and much lower than their EB-PVD counterparts. The TBCs exhibited excellent resistance to thermal shock up to 400 cycles of 1050 degrees C to room temperature (forced air cooling) +200 cycles of 1100 degrees C to room temperature (forced water quenching). The damage evolution mode of TBC system during the thermal cycling was discussed in the light of the features of microstructural development and phase changes. (c) 2004 Elsevier B.V.
