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.
Abstract
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 estab-lished.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 deposi-tion,and the results were compared with the radiographic testing and penetrant testing.The effectiveness of this testing pro-cedure was verified.
