摘要
通过工件底波并结合多次界面反射回波的分析,利用对比试块作出缺陷当量-底波波幅曲线,对粉末冶金铜基合金层及复合面缺陷进行定量检测。
On the basis of analysing backwall echoes and multiple interface echoes,quantitative evaluation of cladding defects and defects in copper based clad alloy has been carried out by using defect equivalence-backwall echo height curve.
