摘要: A permanent magnet of the neodymium-iron-boron type having improved corrosion resistance imparted by a combination oxygen, carbon and nitrogen. Oxygen is provided in an amount equal to or greater than 0.6 weight percent with 0.05-0.15 nitrogen 0.15 maximum. Preferably, oxygen within range 0.6-1.2% 0.05-0.1% 0.02-0.15 more preferably 0.04-0.08 percent. The may be heated argon atmosphere thereafter quenched either further improve magnet.
