Keyword:  钼酸盐缓蚀剂动电位慢扫描;
Abstract: 用动电位慢扫描法研究了钼系缓蚀剂在去离子水中和含5ppm Cl-的去离子水中对A3钢的缓蚀性能,并与200ppm的K2CrO4在同样条件下对A3钢的缓蚀性能作了比较.在5ppm Cl-的去离子水的敞开体系中,100ppm Na2MoO4的缓蚀性能与200ppm的K2CrO4相当;复合缓蚀剂Na2MoO4(12ppm)+NaNO2(23ppm)+ZnSO4(5ppm)+十二酰基肌氨酸钠(100ppm)的性能优于200ppm K2CrO4; 复合缓蚀剂Na2MoO4(86ppm)+Na2SiO3(114ppm)的性能显著优于200ppm的K2CrO4.
