摘要
利用水浸超声C扫描检测系统对钛合金激光直接沉积结构件进行水浸超声检测,并制定了相应的检测工艺,结果表明,该检测工艺具有高灵敏度及高信噪比的特点。将该检测工艺应用到多种钛合金激光直接沉积产品超声检测中,同时和射线检测及渗透检测结果进行了对比,验证了该检测工艺的有效性。
The water-immersion ultrasonic detection of titanium alloy structural component by direct laser deposition was conducted using water-immersion ultrasonic C-scan testing system.The corresponding testing procedures were also established.The results showed that the testing procedure had the characteristics of high sensitivity and high signal-to-noise ratio.The proposed testing procedure was applied to the ultrasonic detection of some titanium alloy products by direct laser deposition,and the results were compared with the radiographic testing and penetrant testing.The effectiveness of this testing procedure was verified.
