Description

шаровой мельнице. Полученный порошок ориентируют в магнитном поле напр женностью 30 кэ и уплотн ют давлением 10 т/см. Спрессованные брикеты спекают при 1120° С в течение часа, охлаждают до 900° С со скоростью 2° С/мин и охлаждают до комнатной температуры со скоростью 500-750° С/мин.ball mill. The resulting powder is oriented in a magnetic field with a strength of 30 ke and compacted with a pressure of 10 t / cm. Compressed briquettes are sintered at 1120 ° C for an hour, cooled to 900 ° C at a rate of 2 ° C / min, and cooled to room temperature at a speed of 500-750 ° C / min.

Свойства посто нных магнитов, изготовленных предлагаемым способом,приведены в таблице.The properties of permanent magnets made by the proposed method are shown in the table.

Как видно из данных таблицы, магнитные свойства посто нных магнитов, изготовленных предлагаемым способом, превышают свойства магнитов, изготовленных известным способом.As can be seen from the table, the magnetic properties of permanent magnets manufactured by the proposed method exceed the properties of magnets manufactured in a known manner.
