摘    要:通过优化镁合金活化及浸锌前处理工艺,在前处理后的镁合金AZ31表面上实施电镀铝。采用SEM/EDX以及极化曲线等手段对镁合金表面上的膜层或镀层进行表征。结果表明,可用于离子液体电镀铝的镁合金前处理工序为碱洗、酸洗、HF活化(400mL/L40%HF,10min)、浸锌(20min)、除水工序。通过该工序,可在镁合金表面上获得致密的浸锌层。采用TMPAC-AlCl3离子液体直流电镀铝,可获得致密的银白色电镀铝层。

关 键 词:镁合金  电镀铝  前处理  浸锌  离子液体

Abstract:It is difficult to directly electroplate Al on Mg alloys. The effects of pretreatment parameters on the corrosion resistance of films obtained on AZ31 Mg alloy surface were studied by using potentiodynamic polarization curves, to produce a compact interfacial layer as zinc-immersion deposition. After the substrate was pretreated under optimized conditions, aluminum was electrodeposited on AZ31 from TMPAC-AlCl3 room temperature ionic liquids. The depositions were characterized by scanning electron microscope...
Keywords:magnesium alloys  electroplating  pretreatment procedure  aluminum  ionic liquids
