摘要	The corrosion behaviors of zinc in bulk simulated acid solution and under thin electrolyte layer were studied with an occluded cell which can control the thickness of electrolyte layer. In the bulk simulated acid rain solution with pH value 2.4-3.8, the electrochemical impedance spectroscopy of zinc consists of a capacitive loop in high frequency and an inductive loop in low frequency, the control step for corrosion of zinc is charge transfer process. The corrosion rate and corrosion potential of zinc increase with decreasing pH value of solution. When pH of solution was lower (2.4 and 2.7), the hydrogen bubble absorbed on the surface of zinc was formed due to strong hydrogen process, which made more severely corrosion of zinc around bubble than the other surface of zinc, therefore, the circle trace was formed on the surface of zinc. Under thin electrolyte layer, the corrosion process of zinc changed with thinning electrolyte layer, when the thickness of electrolyte was no more than 100 mum, the control step for corrosion of zinc is a mixed process consisted of charge transfer and diffusion, and the cathodic processes are inhibited and the corrosion rate of zinc decreases with decreasing the thickness of electrolyte layer.
