Abstract
ตัวแม่เหล็กชนิดเผา (sintered magnet body) (Ra T1b Mc Bd ) ที่ถูกเคลือบด้วยสารผสมผง ของสารประกอบเชิงแม่เหล็ก (R1i M1j , R1x T2y M1z, R1i M1j Hk ), โลหะเจือ M1d M2e) หรือผงโลหะ (M1) และออกไซด์ของธาตุแรร์เอิร์ธ (R2) ถูกปฏิบัติด้วยการแพร่ R2 ออกไซด์ถูกรีดิวซ์บางส่วน ระหว่างการปฏิบัติการแพร่ ดังนั้นปริมาณที่มีนัยสำคัญของ R2 สามารถถูกเสริมใกล้หน้าสัมผัสของ เม็ดเสปฐมภูมิภายในแม่เหล็กผ่านช่องทางในรูปของขอบเม็ด แรงลบล้างแม่เหล็กเพิ่มขึ้นขณะที่ลด การเสื่อมของสภาพแม่เหล็กตกค้างลง A sintered magnet body (Ra T1b Mc Bd) coated with a powder mixture. The magnetic compounds (R1i M1j, R1x T2y M1z, R1i M1j Hk), M1d M2e alloy) or metal powders (M1) and rare earth oxides (R2) were treated with R2 diffusion. During the diffusion operation Thus, a significant quantity of R2 can be supplemented near the contact of The primary grain inside the magnet passes through a channel in the form of the edge of the grain. The demagnetization force increases while reducing Deterioration of residual magnetism
