To improve fatigue resistance of SiC fiber-reinforced Ti-15-3 alloy composite, anew interphase layr has been proposed. Duplex metal coatings, Cu/Mo and Cu/W,were deposited on SiC (SCS-6) fiber by PVD process. The fibers were incorporated into Ti-15-3 alloy matrix by HIP process. Fatigue resistance of the un-notched composite and effect of the duplex metal coating on interface mechanical properties were studied. It was found that the duplex metal coatings improved fatigue resistance compared with original SiC fiber-reinforced Ti-15-3 composite. The improvement was achieved by preventing the debonding of SCS coating layr from the SiC fiber by the incorporation of duplex metal coating. Effectiveness of duplex metal interphase layr on the improvement of fatigue resistance in SiC fiber-reinforced Ti-15-3 composite was proved from the experimental evidences.

为了提高SIC纤维增强Ti-15-3合金复合材料的疲劳性耐药性，已经提出了逐渐相间的Layr。通过PVD工艺沉积在SIC（SCS-6）纤维上的双链金属涂层，Cu/Mo和Cu/W。通过髋关节工艺将纤维掺入Ti-15-3合金基质中。研究了未宣传的复合材料的疲劳性和双链金属涂层对界面机械性能的影响。已经发现，与原始的SIC纤维增强Ti-15-3复合材料相比，双链金属涂层改善了抗疲劳性。通过掺入双工金属涂层，通过防止SCS涂料Layr从SIC纤维中进行脱粘来实现改善。双链金属相互相线对SIC纤维增强Ti-15-3复合材料的疲劳耐药性改善的有效性证明了实验证据。
