【摘要】：采用尿素-NaBr-KBr-甲酰胺-ZnCl2離子液體作為鍍液在釹鐵硼磁體表面電鍍鋅,包括基體前處理工藝和鍍后處理工藝,考察了添加劑、供電方式等對(duì)鍍層形貌和耐腐蝕性的影響,通過(guò)中性鹽霧試驗(yàn)、SEM、XRD等對(duì)鍍層進(jìn)行測(cè)試表征。結(jié)果表明:在電流密度1 A/dm2,溫度30℃,電鍍時(shí)間20 min磁力攪拌條件下,當(dāng)添加劑的量為10 mL·L-1時(shí)采用脈沖電鍍電源實(shí)施電鍍,得到的鍍層光亮致密均勻,耐腐性能好。此方法為釹鐵硼磁體電鍍鋅提供了一種新思路。
[Abstract]:Using urea-NaBr-KBr-formamide-ZnCl _ 2 ionic liquid as plating solution, zinc was electroplated on the surface of NdFeB magnets, including pretreatment process and post-plating process. 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，
