摘要 对镁合金表面Ce-Mn和Ce-Mo复合转化膜的性能进行了研究。镁合金Ce-Mo复合转化的最佳配方为:Ce(NO3)39g/L,Na2MoO4 4g/L,C6H5Na3O7·2H2O 2g/L,温度25℃,时间10min。镁合金Ce-Mn复合转化的最佳配方为:Ce(NO3)3 5g/L,KMnO4 2g/L,NH4HF2 0.1g/L,Na2B4O7·10H2O 0.2g/L,温度25℃,时间2min。最优配方下得到的镁合金复合转化膜平整、结晶细致。Ce-Mo复合转化膜的相组成为Mg、MoO2、MoO3、CeO2和Ce2O3;Ce-Mn复合转化膜的相组成为Mg、MgO、MnO2、CeO2和Ce2O3。两种复合转化膜的耐蚀性均比单系转化膜的耐蚀性好,其中Ce-Mo复合转化膜的耐蚀性最好。 The properties of Ce-Mn and Ce-Mo composite conversion films on the surface of magnesium alloy were studied.The optimal formula of Ce-Mo composite conversion process were as follows:Ce(NO3)3 9g/L,Na2MoO4 4g/L,C6H5Na3O7·2H2O 2g/L,temperature 25 ℃,time 10 min.The optimal formula of Ce-Mn composite conversion process were as follows:Ce(NO3)3 5g/L,KMnO4 2g/L,NH4HF2 0.1g/L,Na2B4O7·10H2O 0.2g/L,temperature25℃,time 2 min.The composite conversion film on magnesium alloy obtained with optimal formula was smooth and meticulous.Ce-Mo composite conversion film was composed of Mg,MoO2,MoO3,CeO2 and Ce2O3,and Ce-Mn composite conversion film was composed of Mg,MgO,MnO2,CeO2 and Ce2O3.The corrosion resistance of two composite conversion films was better than that of single-system conversion film,and Ce-Mo composite conversion film exhibited the best corrosion resistance.
