摘要

This paper describes recent progress on research into improving the thermal cycling behavior of thermal barrier coatings. Commercially available NiCrAlY powder was mechanically cryomilled and low pressure plasma sprayed (LPPS) onto a Ni-based alloy. An yttria stabilized zirconia (YSZ) topcoat layer was applied over the NiCrAlY coating using air plasma spray (APS) to produce the thermal barrier coating (TBC) systems. Thermogravimetric analysis (TGA) was used to investigate the oxidation behavior of bond coats made from both commercial and cryomilled powders. Thermal cycling tests were conducted in a high temperature furnace at 1121℃ with a 50 min. holding temperature followed by a 10 min. air cooling period. The TBC system with bond coats made from cryomilled powder showed a significant increase in thermal cycling life (1123 ± 43 cycles) when compared to that of the TBC system with bond coat made from commercial/as-received powder (446 ± 15 cycles). The role of the cryomilling process on the thermal cycling life of the TBC system is discussed in this work.
