Ultrasonic Gauging Technology for High Pressure Tubine Blade

摘要: 针对高压涡轮叶片内腔气冷通道复杂、叶身型面扭角大等特点，选择了合适的超声波测厚仪及探头，制作了超声测厚标准件、叶片空间点定位模板。通过对叶片叶身测量点进行超声测厚工艺试验，确定了高压涡轮叶片超声测厚工艺参数。经与计量检测结果对比、分析，证明了超声测厚结果准确、可靠。

Abstract: Due to the characteristics of high-pressure turbine blade, such as the complex cavity channels and large torsion angle, appropriate ultrasonic c thickness gauge, probe, standard part and positioning template are therefore selected. Through ultrasonic thickness measurement experiments on measuring point of blade, procedures of high-pressure turbine blade ultrasonic thickness measurement is determined. As compared with the real thickness, the ultrasonic thickness results are proved accurate and reliable.
