摘要
本文提出了一种新型超声耦合方法——自耦合方法,磁性耦合剂由磁性探头所吸附进行检测。不仅可大大简化耦合剂涂抹操作、减少耦合剂在工件上的流失损耗,而且提高了检测灵敏度,在超声检测领域具有广阔的应用前景。
A new self-coupling method for ultrasonic testing has been brought up, with which the magnetic couplant can be hold by the magnetic transducers. The method can not only simplify the operating procedure and reduce the loss of couplant,but also raise the sensitivity of testing. So it has great potential in ultrasonic testing
