comSensitivity analysis of nondestructive magnetictechniques for the restoration of stamped markson low carbon steel
تجزیه و تحلیل حساسیت تکنیکهای مغناطیسی غیر مخرب برای بازسازی مهر فولادی کم کربن مارکسون-2020 Restoration of obliterated stamped marks is a common investigative technique used incriminal investigation. Considering the evolution of the obliteration techniques used bycriminals, a study of the feasibility of sensitive, effective, and nondestructive techniques isneeded. This study aims to evaluate the performance and sensibility of two nondestructivetechniques: magnetic particle restoration and magneto-optical imaging. To this end, steelsamples from automobile chassis were analyzed. The samples were characterized in orderto obtain information regarding material microstructure, magnetic characteristic, and hard-ness, followed by the restoration of stamp marks. Both magnetic particle restoration andmagneto-optical imaging were capable of partially restoring the identification code obliter-ated by overstamping. In addition, nondestructive techniques showed a restoration depthlimit of 260 m below the cavity. Keywords:Restoration | Sensibility | Obliterated marks | Magneto-optic imaging | Magnetic particle |
