Description
Как известно, при намагничивании издели из парамагнитного материала, в случае неоднородной структуры .последнего , т.-е. наличи в нем различного рода дефектов: трещин, раковин и т. п., имеют место потоки рассе ни . Поэтому , обычно, дл определени этих дефектов из парамагнитного материала подвергают намагничиванию, после чего определ ют тем или иным индикатором (индукционный .метод, железные опилки и т. д.) величину и место нахождени потоков рассе ни в различных местах поверхности исследуемого предмета. Согласно предлагаемому изобретению, в качестве такого индикатора применена катодна трубка по типу осциллографа.As is well known, when magnetizing a product from a paramagnetic material, in the case of a non-uniform structure, the latter, that is, the presence of various kinds of defects in it: cracks, cavities, etc., there are scattered flows. Therefore, it is usual to magnetize these defects from a paramagnetic material, after which an indicator (induction method, iron filings, etc.) is determined by the amount and location of the scattered fluxes in various places on the surface of the object under study. According to the invention, an oscilloscope-type cathode tube is used as such an indicator.
На чертеже изображена схема устройства дл осуществлени предлагаемого способа.The drawing shows a diagram of an apparatus for carrying out the proposed method.
Подлежаща исследованию железна плита / имеет раковину 2, вызывающую возникновение потоков рассе ни 3. Дл определени этого потока рассе ни , а, следовательно, и места нахождени раковины служит катодна трубка 4, снабженна флуоресцирующим экраном.The iron plate to be examined / has a shell 2, which causes the occurrence of streams of dispersion 3. To determine this dispersion flow, and, consequently, the location of the shell is the cathode tube 4, equipped with a fluorescent screen.

При приближении трубки 4 к раковине 3 катодный пучок 7, под вли нием потока рассе ни , отклонитс в ту или другую сторону, вследствие чего соответственно сместитс свет ща с точка на экране. По смещению этой точки можно судить о наличии дефектов в материале плнты.When tube 4 approaches the shell 3, the cathode beam 7, under the influence of the scattering flow, deviates to one side or the other, as a result of which the light shifts from the point on the screen. By the displacement of this point, it is possible to judge about the presence of defects in the material plnty.
Вместо флуоресцирующего экрана трубка 4 может быть снабжена металлическим кольцевым электродом 8, расположенным так, чтобы отклонение электронного потока вызывало изменение тока в цепи соединенного с электродом измерительного прибора 9.Instead of a fluorescent screen, the tube 4 can be equipped with a metal ring electrode 8 arranged so that the deviation of the electron flux causes a change in the current in the circuit of the measuring device 9 connected to the electrode.
