    摘要:

    针对目前大型工业CT分辨率受限的问题,本文简述了显微CT技术的概念、原理、技术优势,通过显微CT技术对典型航天材料的检测实例,研究了显微CT技术在小尺寸的航天材料检测中的优势。结果表明:显微CT技术能够发现材料中微米级的缺陷,能够观察材料中微小缺陷在空间的形貌及分布,并且能通过图像处理软件统计缺陷的尺寸分布,为航天材料无损检测研究提供了新思路。

    Abstract:

    To overcome the resolution limited of large industrial CT, in this article, Micro-CT was introduced, including its concepts, principles and technological superiority. Furthermore, the advantages of Micro-CT in detection of small size aerospace materials were elaborated through examples measured by Micro-CT techniques. Indicating that Micro-CT can detect micron-level defects in materials and their distribution in space, and the size distribution of defects can be counted by image processing software, a new way for the Nondestructive Testing of Aerospace materials was provided by Micro-CT.
