Cette technologie ne fonctionne que sur des m\u00e9taux ferreux (l\u2019acier, par exemple).<\/p>\n

Un puissant aimant est plac\u00e9 dans la r\u00e9gion de la pi\u00e8ce \u00e0 inspecter. Dans la plupart des cas, on utilise un \u00e9lectro-aimant. Car il peut \u00eatre activ\u00e9 et d\u00e9sactiv\u00e9, \u00e0 souhait. De plus, il peut \u00eatre repositionn\u00e9 facilement en fonction de la taille et de la g\u00e9om\u00e9trie de la pi\u00e8ce.<\/p>\n

Des lignes de flux magn\u00e9tique se propagent entre les deux p\u00f4les de l\u2019aimant. Une discontinuit\u00e9 dans le mat\u00e9riau (une fissure, par exemple) va causer une fuite du flux magn\u00e9tique. Une fine vaporisation de particules magn\u00e9tiques est appliqu\u00e9e sur la surface de la pi\u00e8ce et ces particules vont \u00eatre attir\u00e9es dans les r\u00e9gions de fuites magn\u00e9tiques, r\u00e9v\u00e9lant par le fait m\u00eame la pr\u00e9sence de fissures dans le mat\u00e9riau.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.0.6″ global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.0.6″ global_colors_info=”{}”][et_pb_gallery gallery_ids=”239,240,247,241″ posts_number=”12″ db_images_per_row=”3″ dbdb_version=”3.6.6″ zoom_icon_color=”#e5bf20″ hover_overlay_color=”rgba(10,39,86,0.4)” hover_icon=”T||divi||400″ _builder_version=”4.14.1″ caption_font_size=”12px” hover_enabled=”0″ global_colors_info=”{}” show_pagination=”off” sticky_enabled=”0″][\/et_pb_gallery][et_pb_text admin_label=”L\u00e9gende” _builder_version=”4.0.6″ text_font=”||on||||||” text_font_size=”11px” text_line_height=”1em” custom_margin=”-4px||0px||false|false” custom_padding=”0px||0px||false|false” global_colors_info=”{}”]<\/p>\n
