ECT를 이용한 마르텐사이트 재질의 균열결함 깊이측정 연구
A Study on the Crack Depth Sizing Using ECT Technique for Martensitic Stainless Steel
- 발행 : 2009.12.01
초록
The flaws detected by the non-destructive surface test methods shall be sized by means of the volumetric test such as an UT(ultrasonic test) or an ECT(eddy current test) for the purpose of analyzing and repairing them. It is generally known that the ECT is a comparatively effective technique for the small size cracks which are located shallowly from the surface. On this study, the ECT technique was tried to size the depth of the crack-like EDM notches, and it is identified that the ECT is an appropriate depth sizing technique for the shallow cracks less than 3mm in the Martensitic CA6NM material.
