摘　　要：本文主要研究如何利用超声纵波对 Cu W复合材料的质量进行检测。第一部分根据 Cu W复合材料的缺陷特点 ,分步采用垂直粗探伤法和衰减精探伤法对 Cu W复合材料进行探伤 ;对比分析了探伤过程中灵敏度的确定、探头的选择以及不同牌号材料的探伤问题 ,从而确定了对 CuThis article has investigated how to carry out ultrasonic examination (UE) for W Cu composite by means of ultrasonic examination. According to the features of possible flaws in W Cu composite, the first part mainly studied the rational ways to detect flaws in W Cu composite, which comprise two reliable steps of normal beam testing and damping testing. Furthermore, the UE sensitivity, the parameters of normal probe and the UE for different compositions of W Cu composite have been analyzed, by which the reliable UE methods and related optimum parameters were decided.
