| 1 | Evaluation of Oxidation of Ti-Al and Ti-Al-Cr Coatings Arc-ion Plated on Ti-60 High-temperature Titanium Alloy显示文摘High-temperature titanium alloy for aeroengine compressor applications suers from high-temperature oxidation and environmental corrosion,which prohibits long-term service of this kind alloy at temperatures above 600-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 di-raction(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-C,but poorer resistance against oxidation at 900-C.By contrast Ti-48Al-12Cr coating demonstrated excellent isothermal oxidation resistance at both temperatures. Cyclic oxidation tests performed at 800-C indicated that both coatings demonstrated good cyclic oxidation resistance and no spallation of coatings was observed.But at 900-C only Ti-48Al-12Cr coating demonstrated excellent cyclic oxidation resistance. | Wei Yan Qingjiang Wang Jianrong Liu Shaoqiang Li Fengjiu Sun | 2009 | Journal of Materials Science & Technology2009，25，5： | 1 |
