Abstract:The ionic liquid CO(NH2)2-NaBr-KBr-CH3NO-ZnCl2 was adopted for electroplating zinc on NdFeB magnet. All the pre-processing of the matrix, the solvents and power supply were authenticated through experiments and the coating was characterized by means of neutral salt spray experiment, SEM and XRD. The results show that when the current density is 1 A/dm2, the temperature 30 oC, the electroplating time 20 min and the additives 10 mL·L-1, a comparatively bright, uniform zinc coating with good corrosion resistance can be obtained by means of digital pulse plating power supply. Therefore it supplies a new idea for electroplating of zinc on NdFeB magnet.
