| 中文摘要 | High-temperature titanium alloy for aeroengine compressor applications suffers from high-temperature oxidation and environmental corrosion, which prohibits long-term service of this kind alloy at temperatures above 600 degrees C In an attempt to tackle this problem, Ti-48Al (at pct) and Ti-48Al-12Cr (at pct) protective coatings were plated on the substrate of alloy Ti-60 by arc ion plating (AIP) method. Isothermal and cyclic oxidation tests were performed in static air at elevated temperatures Phase composition, morphology of the coatings and distribution of elements were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX) The results showed that the Ti-48Al coating exhibited good isothermal oxidation resistance during exposure at 800 degrees C, but poorer resistance against oxidation at 900 degrees C By contrast Ti-48Al-12Cr coating demonstrated excellent isothermal oxidation resistance at both temperatures Cyclic oxidation tests performed at 800 degrees C indicated that both coatings demonstrated good cyclic oxidation resistance and no spallation of coatings was observed But at 900 degrees C only Ti-48Al-12Cr coating demonstrated excellent cyclic oxidation resistance |
