Изобретение относитс к радиотехнике, в частности к технике защиты от помехонесущих магнитных полей, и может быть использовано при изготовлении магнитных экранов дл электронноонтических приборов и высокочастотных устройств.The invention relates to radio engineering, in particular, to a technique of protection against disturbing magnetic fields, and can be used in the manufacture of magnetic screens for electron-beam devices and high-frequency devices.
Известные способы изготовлени магнитных экранов из пермалло , основанные на гибке заготовок с последующим отжигом, характеризуютс деформацией экрана при отжиге.The known methods for the manufacture of permallo magnetic screens based on the bending of the workpieces with subsequent annealing are characterized by the deformation of the screen during annealing.
Цель изобретени - повышение качества экранов.The purpose of the invention is to improve the quality of the screens.
Это достигаетс тем, что изготовл ют жесткую оболочку магнитного экрана из материала , температура плавлени которого выще температуры плавлени пермалло , образу в ней неразъемное соединение, после чего производ т отжиг.This is achieved by making a hard shell of a magnetic screen from a material, the melting point of which is higher than the melting point of permallo, forming a permanent joint in it, after which it is annealed.
По предлагаемому способу изготовл ют жесткую оболочку магнитного экрана из материала , температура плавлени которого не менее, чем на 150-200°С, выще температурыAccording to the proposed method, a hard shell of a magnetic screen is made of a material whose melting point is not less than 150-200 ° C, higher than
плавлени пермалло , а коэффициент линейного расщирени близок к коэффициенту линейного расщирени пармалло . Внутреннюю поверхность оболочки выстилают пермаллоем, который жестко соедин ют с оболочкой (например , точечной или аргонодуговой сваркой, клепкой и т. п.), затем подвергают отжигу в соответствии с технологией термообработки пермалло .melting permallo, and the coefficient of linear expansion is close to the coefficient of linear expansion of parmallo. The inner surface of the shell is lined with permalloy, which is rigidly connected to the shell (for example, spot or argon-arc welding, riveting, etc.), then subjected to annealing in accordance with the thermal processing technology of permallo.
