Изобретение относитс  к способам получени  ферритовых изделий методом порошковой металлургии.This invention relates to methods for producing ferrite products by powder metallurgy.

Известный способ предусматривает изготовление ферритов погружением отпрессованных изделий в расплав стекла с последующим их обжигом иа воздухе или в вакууме.The known method involves the manufacture of ferrites by dipping the pressed products into the glass melt with their subsequent roasting with air or in vacuum.

Указанный способ дл  защиты от окислени  требует частично или полностью защитной атмосферы или вакуума во врем  загрузки (выгрузки ) или закалки после выгрузки. Это вызывает применение сложных устройств дл  погружени  отпрессованных заготовок в расплав с температурой 1200-1400°С и дл  выемки из него или дл  создани  вакуума в процессе обжига.This method of protection against oxidation requires a partially or fully protective atmosphere or vacuum during loading (unloading) or hardening after unloading. This causes the use of complex devices for immersing pressed blanks into the melt with a temperature of 1200-1400 ° C and for withdrawing it or for creating a vacuum in the firing process.

С целью исключени  окислени  и снижени  механических напр жений, предложен способ изготовлени  ферритовых изделий, который отличаетс  от известного тем, что на спрессованные издели  нанос т при комнатной температуре защитную пленку, содержащую тонкоизмельченный полевой шпат и ферритор того же состава, что и обрабатываемый материал.In order to eliminate oxidation and reduce mechanical stresses, a method has been proposed for manufacturing ferrite products, which differs from the well-known one in that a pressed film is applied to a pressed product at room temperature containing finely divided feldspar and a ferrite of the same composition as the material being processed.

Дл  получени  изделий, например, маргаицево-цинковые ферриты формуют любымTo obtain products, for example, margaite-zinc ferrites are molded by any

известным способом. На спрессованное изделие нанос т любым методом (погружением, пульверизацией и т. д.) тонкий слой суспензии, содержащей 70-80% тонкоизмельченного полевого шпата и 20-30% феррита того состава, что и спрессованное изделие. В качестве св зки защитной массы быть, например , раствор поливинилового спирта. После подсушки издели  обл игают в воздушной атмосфере по температурному режиму, заданному дл  данной марки феррита. При обжиге на воздухе образуетс  па поверхности ферритового издели  тонка  зашитна  пленка, предохран юща  марганец от окислени .in a known way. A thin layer of a suspension containing 70–80% finely divided feldspar and 20–30% ferrite of the same composition as the pressed product is applied to the compacted product by any method (by immersion, spraying, etc.). As a protective mass binder, for example, a solution of polyvinyl alcohol. After the product has been dried, it is swept in air in accordance with the temperature conditions specified for this type of ferrite. When fired in air, a thin protective film is formed on the surface of the ferrite product, protecting manganese from oxidation.

Предмет изобретени Subject invention

Способ изготовлени  феррптовых изделий, включающий прессование и спекание на воздухе , отличающийс  тем, что, с целью исключени  окислени  и снижени  механических напр жений , на спрессованные издели  нанос т при комнатной температуре защитную пленку, состо щую из тонкоизмельченного полевого шпата и феррита того же состава, что и обрабатываемый материал.A method of manufacturing ferrite products, which includes pressing and sintering in air, characterized in that, in order to eliminate oxidation and reduce mechanical stresses, a protective film is applied to the pressed products at room temperature, consisting of finely divided feldspar and ferrite of the same composition, as the material being processed.
