摘要
以含有不同质量浓度Y(NO3)3·6H2O的双[γ-(三乙氧基硅)丙基]四硫化物硅烷(BTESPT)半水解液为处理液,采用浸渍提拉法在AZ31B镁合金表面制备了钇掺杂的硅烷膜。采用电化学工作站、扫描电镜、X射线衍射仪和红外光谱仪研究了钇掺杂对硅烷膜耐蚀性、表面形貌和组织结构的影响。结果显示,钇掺杂能够减少硅烷膜的微孔,提高硅烷膜的耐蚀性。硅烷溶液中Y(NO3)3·6H2O的质量浓度为12 g/L时,所得钇掺杂硅烷膜的耐蚀性最佳。
Yttrium-doped silane films were prepared on AZ31B magnesium alloy surface by dip coating from a semihydrolyzed bis(triethoxysilypropyl)tetrasulfide(BTESPT)solution with different mass concentrations of Y(NO3)3·6H2O.The effect of yttrium doping on the corrosion resistance,surface morphology,and microstructure of silane film was studied using electrochemical workstation,scanning electron microscope,X-ray diffractometer,and infrared spectrometer.The results showed that the corrosion resistance of silane film could be improved by yttrium doping due to the reduction of micropores.The yttrium-doped silane film obtained from the BTESPT solution containing 12g/L of Y(NO3)3·6H2O had the best corrosion resistance.
