PDC的超声检测

STUDY ON ULTRASONIC TESTING OF POLYCRYSTALLINE DIAMOND COMPOSITES

本文简要介绍了使用超声波技术对金刚石复合片 (PDC)进行检测的一些初步体会 ,对应用超声波A扫描、C扫描方法在检测过程中应注意的问题进行了描述。特别对使用超声波C扫描法在 10MHz、5 0MHz和 10 0MHz频率下检测PDC时出现的部分现象及结果进行了简要的说明 ,这些现象和结果对今后的研究具有一定的参考作用。

The paper made a brief introduction to the testing of polycrystalline diamond composites (PDC) using ultrasonic technology,and also analyzed some problems in the testing process using ultrasonic A-Scan & C-Scan.It espcially explained some phenomena and results in testing PDC with C-scan under 10MHz,50MHz and 100MHz,and found the regular results accordingly,which would be referential information for further rusearch.
