研究了涂覆单一涂层Ｙ２Ｏ３或Ａｌ２Ｏ３的Ｔｉ纤维增强γＴｉＡｌ基复合材料的界面和性能。运用物理气相沉积法在Ｔｉ纤维表面涂覆Ｙ２Ｏ３或Ａｌ２Ｏ３涂层后，然后用类似箔叠法制得ＴｉＹ２Ｏ３γＴｉＡｌ和ＴｉＡｌ２Ｏ３／γＴｉＡｌ复合材料。复合材料的弯曲强度从４４９ＭＰａ提高到５６２ＭＰａ（ＴｉＹ２Ｏ３／γＴｉＡｌ）或５７３ＭＰａ（ＴｉＡｌ２Ｏ３／γＴｉＡｌ），而且高于纯Ｔｉ纤维增强ＴｉＡｌ基复合材料的弯曲强度。纤维与基体间的界面反应层厚度由３０μｍ（Ｔｉ／γＴｉＡｌ）减少为１４μｍ（ＴｉＹ２Ｏ３／γＴｉＡｌ）或２０μｍ（ＴｉＡｌ２Ｏ３／γＴｉＡｌ）。 The interface and properties of Ti-fiber reinforced γ-TiAl-based composites coated with a single coating of Y2O3 or Al2O3 were studied. The physical vapor deposition method is used to coat the surface of Ti fiber with Y2O3 or Al2O3 coating and then the Ti-Y2O3  γTiAl and TiAl2O3 / γTiAl composites are prepared by using the similar foil stacking method. The flexural strength of composites increased from 449MPa to 562MPa (TiY2O3 / γTiAl) or 573MPa (TiAl2O3 / γTiAl), and higher than that of pure Ti fiber reinforced TiAl matrix composites. The thickness of the interface reaction layer between fiber and matrix was reduced from 30μm (Ti / γ-TiAl) to 14μm (TiY2O3 / γTiAl) or 20μm (TiAl2O3 / γTiAl).
