    摘要:

    研究了Cu/Al復(fù)合添加對(Pr, Nd)12.8Dy1.0FebalNb0.1B6.0 (at%)燒結(jié)磁體抗腐蝕性和磁性的影響。結(jié)果表明：添加0.6 at% Al和0.2 at% Cu時磁體的抗腐蝕性最強(qiáng)，磁體在0.001 mol/L HCl溶液中的腐蝕電流密度從46.90 μA·cm-2降低到11.14 μA·cm-2，在濕熱環(huán)境中腐蝕100 h的質(zhì)量損失從13.2 mg·cm-2降低到0.4 mg·cm-2?？垢g性的提高源于Cu和Al對富(Pr, Nd)晶界相化學(xué)穩(wěn)定性的提高及其分布狀況的改善。同時，Cu/Al對燒結(jié)NdFeB晶界結(jié)構(gòu)的優(yōu)化也有利于磁體磁性能的提高

    Abstract:

    Effects of Cu/Al compound addition on the anti-corrosive and magnetic properties of (Pr, Nd)12.8Dy1.0FebalNb0.1B6.0 (at%) sintered magnets were investigated. It is found that the corrosion current density decreases from 46.90 μA·cm-2 for the magnet without Cu/Al to 11.14 μA·cm-2 for the magnet with additions of 0.6 at% Al and 0.2 at% Cu in 0.001 mol/L HCl solutions, the mass loss reduces from 13.2 mg·cm-2 to 0.4 mg·cm-2 in hot/humidity atmosphere for 100 h. The 0.6 at% Al- and 0.2 at% Cu-added magnet has the maximum corrosion resistance. The improvement of the corrosion resistance can be ascribed to the enhanced chemical stability and the optimized distribution of (Pr, Nd)-rich grain boundary phase. Additionally, the optical grain boundary microstructure is benefit for the magnetic properties
