Modification of the magnetic properties and corrosion resistance of Nd-Fe-B permanent magnets with addition of cobalt

The effect of partial substitution of iron by cobalt on the Curie temperature, demagnetization curves and corrosion behaviour under various conditions of sintered Nd 16Fe 76−xCo xB 8 ( O ⩽ x ⩽ 30) permanent magnets was investigated. The microstructure and chemical composition of phase structures wer...

Zusammenfassung:	The effect of partial substitution of iron by cobalt on the Curie temperature, demagnetization curves and corrosion behaviour under various conditions of sintered Nd 16Fe 76−xCo xB 8 ( O ⩽ x ⩽ 30) permanent magnets was investigated. The microstructure and chemical composition of phase structures were also determined. A new intergranular Nd(Fe, Co) 2B 2 phase was found for x ⩾ 20.
