METHOD OF MAGNETIC-TAPE TEST OF ARTICLES WITH SMALL- CURVATURE SURFACE OF MAGNETICALLY SOFT STEELS Russian patent published in 1997 - IPC

Abstract RU 2097758 C1

FIELD: nondestructive test. SUBSTANCE: when article under test is magnetized along with magnetic tape positioned on its surface by permanent magnet with field H_O, use is made of tapes with starting field H_B not less than 250-300 A/cm. Tape with maximum value of saturating field H_S is selected of all suitable tapes. Value H_O is selected equal to value H_B, and article quality is determined by results of magnetogram reading. EFFECT: higher test results. 3 dwg
