Abstract
แม่เหล็กถาวรที่มีแรร์เอิร์ธได้รับการเตรียม โดยการจัดเตรียมวัตถุแม่เหล็กที่ได้รับการเผา ผนึกซึ่งประกอบด้วยแรร์เอิร์ธ 12-17% อะตอม, B 3-15% อะตอม, ธาตุที่เป็นโลหะ 0.01-11% อะตอม, O 0.1-4%, C 0.05-3% อะตอม, N 0.01-1% อะตอม และดุลด้วย Fe , การจัดวางผงซึ่ง ประกอบด้วยออกไซด์ ฟลูออไรด์และ/หรือออกซีฟลูออไรด์ของแรร์เอิร์ธอื่นบนผิวของวัตถุ แม่เหล็ก และการบำบัดด้วยความร้อนวัตถุแม่เหล็กที่ได้รับการปกคลุมด้วยผงที่อุณหภูมิต่ำกว่า อุณหภูมิการเผาผนึกในสุญญากาศหรือในแก๊สเฉื่อย เพื่อเป็นเหตุให้แรร์เอิร์ธอื่นถูกดูดซึมในวัตถุ แม่เหล็ก Permanent magnet with rare earth has been prepared. By providing a sintered magnetic object Seals containing 12-17% Rare Earth Atom, B 3-15% Atom, 0.01-11% Metal Element, 0.1-4% O atom, C 0.05-3% Atom, N 0.01-1% Atom. And balance with Fe, a powder placement which Oxides Other rare-earth fluoride and / or oxyfluoride on the surface of the magnetic object and the magnetic object heat treatment that has been covered with powder at a lower temperature. Sintering temperature in vacuum or inert gas To cause other rare earth to be absorbed in magnetic objects
