- W2894979010 abstract "以HAST加速寿命试验后磁体失重，以及在不同腐蚀介质中磁体动电位极化曲线为表征，研究稀土元素Nd取代Pr对烧结Pr-Nd-Fe-B磁体耐腐蚀性的影响.结果表明：用Nd完全取代Pr后，磁体失重减小，室温下在0.1 mol/L HCl溶液、3.0 % NaOH溶液、3.5 % NaCl溶液中腐蚀电位不同程度地正移，表明磁体耐腐蚀性得到改善.通过场发射扫描电子显微镜观察HAST试验后磁体的微观组织形貌发现，Nd取代Pr后，晶界分布变得更加连续、清晰，且晶界交隅处的富稀土相含量减少，从而延缓了晶界腐蚀速率，使磁体的总体耐腐蚀性得到提升." @default.
