【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1 A/dm2,温度30℃,电镀时间20 min磁力搅拌条件下,当添加剂的量为10 mL·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。

The effects of additives and power supply methods on the morphology and corrosion resistance of the coating were investigated. The coating was characterized by neutral salt spray test and SEM XRD. The results show that under the conditions of current density 1 A / dm 2, temperature 30 鈩，
