Dy Electrodeposition on Sintered Nd-Fe-B

Dy Electrodeposition on Sintered Nd-Fe-B

A low-cost, high-efficiency electrodeposition technique was used to enhance the coercivity of Nd-Fe-B. Dy was electrodeposited on the surface of a sintered Nd-Fe-B magnet in a nonaqueous solution. The use of the organic solvent dimethylformamide results in improved electrodeposition and adhesion com...

Zusammenfassung:A low-cost, high-efficiency electrodeposition technique was used to enhance the coercivity of Nd-Fe-B. Dy was electrodeposited on the surface of a sintered Nd-Fe-B magnet in a nonaqueous solution. The use of the organic solvent dimethylformamide results in improved electrodeposition and adhesion compared to ethanol. A dense deposition layer was achieved when current density was
