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 Nd16Fe76−xCoxB8 (O ⩽ x ⩽ 30) permanent magnets was investigated. The microstructure and chemical composition of phase structures were also determined. A new intergranular Nd(Fe, Co)2B2 phase was found for x ⩾ 20.
