用电化学极化曲线和电化学阻抗法研究了304不锈钢在垃圾渗滤液中的腐蚀行为.结果表明，在垃圾渗滤液中，不锈钢的腐蚀电位在-0.30~-0.60 V范围内波动，浸泡888小时后，平均腐蚀电流密度为2.829 μA/cm2；不锈钢在垃圾渗滤液中具有良好的抗腐蚀性能，主要是由其表面活性点钝化引起的，并非钝化膜的阻隔作用.
The corrosion behavior of 304 stainless steel in a waste percolate was investigated by means of polarization curve and electrochemical impedance spectroscopy(EIS).The corrosion potential of the steel sample ranged from -0.30 V to -0.60 V in the waste percolate. Immersed in the waste percolate for 888 h,the average corrosion current density of the sample was of 2.829 μA/cm2.The good anticorrosion performance of stainless steel in the waste percolate could be mainly attributed to the passivation of the surface active sites,instead of the barrier effect of the passive film.
