A nondestructive method for detecting cracks and other discontinuities at or near the surface in ferromagnetic materials. Finely divided magnetic particles are applied to the surface of a part which has been suitably magnetized. The particles are attracted to regions of magnetic nonuniformity associated with defects and discontinuities, thus producing indications which are observed visually.... 7, record 1, English, - magnetic%20particle%20inspection

Le contrôle magnétoscopique s’applique exclusivement aux pièces en alliage ferromagnétique. Dans une telle pièce, supposée aimantée, une solution de continuité [...] crée une fuite magnétique. Par la suite de la réfraction magnétique, [...] les lignes d’induction sortent de la pièce [...] et dessinent dans l'atmosphère environnante un champ à forte courbure. Des particules ferromagnétiques [...] remontent les lignes d’induction pour se plaquer à la surface, où elles dessinent par leur accumulation un spectre élargi de la solution de continuité : l'élargissement apparent est d’autant plus important que la perturbation du champ est plus intense c'est-à-dire que le défaut qui la crée est de section relative plus forte(en fait plus étendu en profondeur). 1, record 1, French, - contr%C3%B4le%20magn%C3%A9toscopique

The magnetic particle method is the most satisfactory method for finding surface and sub-surface defects. ... The basic principle of the method is that while magnetic flux lines are caused to flow in a part, the local disturbance at a flaw is detected by using a magnetic powder either dry, or preferably, as a suspension in a liquid. Ferroso-ferric oxide (magnetic oxide of iron, Fe3 04 is generally preferred to powdered soft iron although even iron filings will indicate the larger faults. 1, record 2, English, - powdered%20iron

En projetant à la surface d’une pièce défectueuse de fines particules magnétiques, celles-ci sont attirées et accumulées par le champ de fuite qui se comporte à leur égard comme un minuscule aimant. Cette accumulation visible des particules donne ce que l'on nomme le "spectre du défaut". Ces particules sont généralement des oxydes magnétiques, plus rarement de la poudre de fer. 1, record 2, French, - poudre%20de%20fer
