| 摘 要： | 本文是CuW复合材料的超声波探伤研究的第二部分。主要研究了如何利用超声波探伤法检测CuW／CuCr(Cu)整体触头结合面的方法。对比选择了超声探测面，分析了CuW／CuCr(Cu)结合面探伤特点，并着重针对结合面氧化缺陷，对比采用B／S法和采用单独比较结合面反射渡法的探伤效果，提出了采用单独比较结合面反射波法对CuW／CuCr(Cu)结合面进行探伤的参数，并给出了相应的检测效果图。

| Abstract: | The second part mainly studied how to evaluate the binding course of CuW/CuCr(Cu)contactor by ultrasonic examination. As the succession of the former part, this part mainly discussed the practical ways to evaluate the possible flaws in W-Cu composite through multiple echo method and normal scanning beam testing method by using reference blocks. According to the real testing practice ,rational ways to operate the testing methods and evaluate flaws in W-Cu composite were given by the reference of standard sound waves and the typical flaws' waves. |
