中文摘要：
采用尿素．NaBr—KBr-甲酰胺．ZnCl2离子液体作为镀液在钕铁硼磁体表面电镀锌，包括基体前处理工艺和镀后处理工艺，考察了添加剂、供电方式等对镀层形貌和耐腐蚀性的影响，通过中性盐雾试验、SEM、XRD等对镀层进行测试表征。结果表明：在电流密度1A／dm2，温度30℃，电镀时间20min磁力搅拌条件下，当添加剂的量为10mL·L^-1时采用脉冲电镀电源实施电镀，得到的镀层光亮致密均匀，耐腐性能好。此方法为钕铁硼磁体电镀锌提供了一种新思路。
英文摘要：
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℃, the electroplating time 20 rain 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.
