一种离子液体添加剂在瓦特电镀镍溶液中的应用
摘要：
本发明公开了属于电镀技术领域的一种离子液体添加剂在瓦特电镀镍溶液中的应用。在常规电镀中的瓦特镍溶液中加入离子液体添加剂和络合剂，电镀液中离子液体添加剂浓度为0.1～15g/L，络合剂浓度为1～60g/L，电镀液pH值为0.5～7，电流密度为1～50A/dm2，在温度10～80℃下在导电基底上电镀镍层。本发明能够在导电基底上提供优质的镍镀层。在本发明的方法制备出的镍镀层具有较高的硬度和优良的耐蚀性能。镍镀层的显微硬度HV0.02在380以上，在0.5M NaCl溶液中的腐蚀速率为在0.10mg·dm-2h-1以下。
摘要（英）：

The invention discloses application of an ion liquid addictive in a watt nickel electroplating bath, belonging to the technical field of electroplating. The application is realized by the steps of: adding an ion liquid addictive and a complexing agent into a conventionally-electrplated watt nickel bath and electroplating a nickel layer on a conductive substrate at the temperature of 10-80 DEG C, wherein the concentration of the ion liquid addictive in the electroplating bath is 0.1-15g/L; the concentration of the complexing agent is 1-60g/L; the pH value of the electroplating bath is 0.5-7; and the current density is 1-50A/dm<2>. The invention can provide the nickel electroplating layer with high quality on an inductive substrate. The nickel electroplating layer prepared by the method hashigher hardness and excellent corrosion resistant performance. The microhardness HV0.02 of the nickel electroplating layer is over 380; and the corrosion speed of the nickel electroplating layer in 0.5M NaCl solution is 0.10mg<-2>h<-1>.
