| 中文摘要 | Initial atmospheric corrosion of zinc in the presence of Na2SO4 and (NH4)(2)SO4 was investigated via quartz crystal microbalance(QCM) in laboratory at relative humidity(RH) of 80% and 25 degrees C. The results show that both Na2SO4 and (NH4)(2)SO4 can accelerate the initial atmospheric corrosion of zinc. The combined effect of Na2SO4 and (NH4)2SO4 on the corrosion of zinc is greater than that caused by (NH4)(2)SO4 and less than that caused by Na2SO4. Fourier transform infrared spectroscopy(FTIR), X-ray diffractometry(XRD) and scanning electron microscopy(SEM) were used to characterize the corrosion products of zinc. (NH4)(2)Zn(SO4)(2), Zn4SO4(OH)(6)center dot 5H(2)O and ZnO present on zinc surface in the presence of (NH4)(2)SO4 while Zn4SO4(OH)(6)center dot 5H(2)O and ZnO are the dominant corrosion products on Na2SO4-treated zinc surface. Probable mechanisms are presented to explain the experimental results. |
