铸件缺陷无损检测方法的研究现状

Review of Non-destructive Test Methods for Castings Defect

随着汽车业和航天航空业的高速发展 ,铸件的缺陷检测和质量评价已成为工业生产中极其重要的环节。铸件缺陷的检测方法及相关技术的研究也取得了很多成果。文中对目前广泛使用且效果较好的超声检测。

With the rapid development in car industry, aerospace and aviation, the defects testing and quality evaluation for castings have become significant steps in the industrial production. And many achievements have been acquired in the field of castings defect testing and relevant techniques. This paper summarizes the effective testing methods, which are widely used currently such as ultrasonic testing, radiography and computed tomography.
