摘要: 采用碳纳米管孕育块铸造法制备碳纳米管/AZ31镁基复合材料,测量其电化学极化曲线,研究碳纳米管加入量对复合材料抗腐蚀性能的影响,利用SEM对复合材料腐蚀前后的表面形貌进行了观察和分析。结果表明,碳纳米管的加入有效地提高了复合材料的抗腐蚀性能,随着复合材料中碳纳米管加入量的增加,腐蚀电流密度Icorr由5.279 μA/cm2减小到2.994 μA/cm2
关键词 碳纳米管AZ31镁合金复合材料腐蚀    
Abstract:Multi-walled carbon nonotubes (MWCNTs) /AZ31 composites were fabricated by joining preform of MWCNTs during melting. The corrosion behaviors of the composites were studied by electrochemical corrosion experiments in 3.5% (mass fraction) NaCl solution. The surface morphologies of the composites before and after corrosion were observed and analysised by SEM. The results showed that additions of MWCNTs improved anticorrosive performances of AZ31 Mg-based alloy, the corrosion current density (Icorr) decreased from 5.279 to 2.994 μA/cm2.
