Материал получают смещением исходных металлических порощков железа, кобальта, хрома и порощка железо-кремниевой лигатуры (45-80% кремни , остальное - железо), прессованием изделий заданной фОрмы и размаров под давлением 6-10 т/см и спеканием полученных прессовок при температуре 1200- 1300°С в течение 2-4 час в вакууме или защитной атмосфере. Спеченные издели могутThe material is obtained by displacing the original metal powders of iron, cobalt, chromium and iron-silicon ligature powder (45-80% silicon, the rest is iron), pressing the products of a given shape and dimensions under pressure of 6-10 t / cm and sintering the resulting compacts at a temperature of 1200 - 1300 ° C for 2-4 hours in a vacuum or protective atmosphere. Sintered products can
быть применены в качестве магнитопроводов.be used as magnetic circuits.
С целью дополнительного повышени свойств или получени изделий особо сложной формы спеченные магпитопроводы могут подвергатьс дополнительной термической обработке - отжигу при температуре пор дка 800-900°С в течение 1-2 час. В некоторых случа х операции прессовани и спекани изделий повтор ют дважды. При особо сложной форме изделий их иногда подвергают ме0 ханической обработке резанием.In order to further improve the properties or to obtain products of particularly complex shape, sintered magpatelines can be subjected to additional heat treatment — annealing at a temperature of the order of 800–900 ° C for 1–2 hours. In some cases, the pressing and sintering operations are repeated twice. In the case of a particularly complex form of products, they are sometimes subjected to mechanical machining.
