| 英文摘要 | The fiber fracture is a very dangerous defect in the aeroengine integral bladed rings which is manufactured by continuous SiC fibers-reinforced titanium alloy matrix composite (Ti-MMC). Currently the lack of an effective method for inspecting the fiber fracture seriously influences the quality control of the aeroengine integral bladed rings, therefore solving the problem of non-destructive testing for deep buried radial micro-cracks is an insurmountable barrier for the application of Ti-MMC integral bladed rings in aviation. In this work, based on the theory of ultrasonic head-waves, the refraction longitudinal waves with the proper angle generated by the creeping wave probe are propagated on the interface, which means the creeping wave with high energy is generated. The finite element simulation model of the creeping wave is established for inspecting the defect of SiC fibers breakage in Ti-MMC aero-engine bling structure. Based on the results of the finite element simulation, significant defect signal waves are generated in the water layer above the defect. After that, not only the ultrasonic propagation characteristics at the interface of multilayer media but also the diffraction phenomenon of the creeping wave when they encounter the broken wire defect are analyzed. And the detection signal amplitude is not only affected by the incident angle of the creeping probe but also is related to the thickness of titanium alloy. In order to receive the diffracted waves with high sensitivity, the assembled probe, which is composed by a creeping wave exciter (5 MHz, 20 degrees) and an immersion focusing sensor (5 MHz, diameter 6 mm), is specially designed and manufactured according to the results of the finite element simulation. In addition, the artificial sample with the broken fiber is prepared and then tested by the ultrasonic C-scan testing system with the assembled probe. The results show that the three-layer broken wire defects (the crack height is about 0.42 mm) with different depths in the artificial sample can be detected successfully. The C-scan results can match the defect positions of the artificial sample which means this detection method is valid. This method is simple, economical and fast, and is expected to solve the problem of nondestructive testing for broken wire in the deep embedded fiber ring in the Ti-MMC aero-engine bling structure. |
