摘　　要：TC17整体叶盘作为发动机进气端关键承力部件,超声检测灵敏度要求高,且检测截面厚度较大,而TC17材质对超声波的衰减较大,导致检测信噪比低,从而影响缺陷的检测。通过理论分析和试验验证,从检测技术、探头选择和扫查方案等方面优化,找到了一种可有效提高检测信噪比的检测工艺方案,在检测过程中避免了噪声的影响,从而保证了缺陷的检出。As the most critical component of air intake end of the engine,the integral blade disk requires high sensitivity in ultrasonic testing,and the thickness of the testing section is relatively large.However,TC17 material has a significant attenuation of ultrasonic waves,resulting in a low signal-to-noise ratio for testing,which affects the detection of defects.In this paper,the detection technology,probe selection,and scanning scheme are optimized through theoretical analysis and experimental verification,and an effective detection process scheme that can improve the signal-to-noise ratio of detection is found to avoid the influence of noise during the detection process,thereby the detection of defects can be guaranteed.
