Изобретение относитс  к области сплавов ка основе системы самарий-кобальт, которые используютс  дл  изготовлени  посто нных магнитов.This invention relates to the field of samarium-cobalt based alloys, which are used in the manufacture of permanent magnets.

Известен сплав дл  посто нных магнитов, состав которого может быть выражен формулой SinCo5.A known alloy for permanent magnets, the composition of which can be expressed by the formula SinCo5.

С целью повышени  сопротивлени  окислению и повышени  стабильности по химическому составу посто нных мапнитов предложен сплав на основе системы самарий-кобальт, в который введено железо при следующем соотношенни компонентов (в вес. %):In order to increase the oxidation resistance and increase the stability of the chemical composition of permanent magnetite, an alloy based on the samarium-cobalt system has been proposed, into which iron has been introduced in the following ratio of components (in wt.%):

Предложенный сплав используетс  в качестве лигатуры при получении посто нного магнита из сплава на основе системы самарий-кобальт-желбзо-медь .The proposed alloy is used as a ligature in the preparation of a permanent magnet from an alloy based on the samarium-cobalt-yellow-copper system.

Снлав, полученный выплавлением в индукционной печи или другим способом в защитной среде, измельчают в порошок с размером частиц 30-150 мк, который затем берут в количестве , обеспечивающем в составе конечного продукта заданное содержание самари , и смешивают с порошками кобальта, железа и меди. Полученную шихту прессуют на воздухе или вSnlav, obtained by smelting in an induction furnace or other method in a protective environment, is ground into a powder with a particle size of 30-150 microns, which is then taken in an amount providing the specified samarium content in the final product, and mixed with cobalt, iron and copper powders. The resulting mixture is pressed in the air or in

защитной , например аргоне, а затем спекают в защитной среде. Использование предложенного сплава - лигатуры обеспечивает производство посто нных магнитов из сплава на основе системы самарий-кобальт-железомедь , стабильных по химическому составу с высокими магнитными свойствами.protective, such as argon, and then sintered in a protective environment. The use of the proposed alloy - ligature ensures the production of permanent magnets from an alloy based on the samarium – cobalt – iron – copper system, stable in chemical composition with high magnetic properties.
