| 中文摘要 | A single sputtered NiCrAlY coating and a complex coating of inner ion-plated TiN and outer sputtered NiCrAlY were prepared on the intermetallic compound Ti3Al-Nb. Their oxidation behavior was examined at 850, 900, and 950 degrees C in air by thermal gravimetry combined with XRD, SEM, and EDAX. The results showed that Ti3Al-Nb followed approximately parabolic oxidation, forming an outer thin Al2O3-rich scale and an inner TiO2-rich layer doped with Nb at the three temperatures. The TiO2-rich layer doped with Nb dominated the oxidation reaction. The single NiCrAlY coating did not follow parabolic oxidation exactly at 850 and 950 degrees C, but oxidized approximately in a parabolic manner, because the instantaneous parabolic constants changed slightly with time. Besides the Al2O3 scale, TiO2 formed from the coating surface at the coating-substrate interface. The deterioration of the coating accelerated with increasing temperature. The NiCrAlY-TiN coating showed two-stage parabolic oxidation at 850 and 900 degrees C, and an approximate parabolic oxidation at 950 degrees C, The TiN layer was effective as a barrier to inhibit coating-alloy interdiffusion. |
