摘　　要：通过电解前后阳极的外观形貌、微观形貌及槽电压,研究不同槽型对电解腐蚀的影响,并以优化后的电解槽研究5Cu/(NiFe2O4-10NiO)金属陶瓷惰性阳极在Na3AlF6-K3AlF6-AlF3-Al2O3电解质中的电解腐蚀。结果表明:电解后阳极存在一定程度的腐蚀,且少量电解质已渗透到阳极中。The effect of different cell types on electrolytic corrosion was studied from macroscopic and microcosmic features and cell voltage,then with optimized cells,electrolytic corrosion of 5Cu/（NiFe2O4-10NiO） cermet inert anode in Na3AlF6-K3AlF6-AlF3-Al2O3 electrolyte was studied.The results show that corrosion occurs to a certain extent to the anode and a little electrolyte penetrates into the cermet.
