在暴露2个月和7个月期间，研究了304L型（UNS S30403）不锈钢的表面处理对城市和海洋环境中耐大气腐蚀性能的影响。研究的表面状况包括原样、酸洗、研磨和光亮退火的样品。在曝光前对表面进行研究，观察不同表面处理之间的表面成分、极化电阻、表面粗糙度和润湿性的差异。在暴露期间，所有样品的重量均下降。在目前条件下，原样样品在城市环境中表现出最佳性能，而光亮退火样品在海洋环境中表现出最佳性能。两种环境下表面处理对耐大气腐蚀性能的不同影响可以通过钝化膜成分的差异来最好地解释。
The influence of surface treatment of Type 304L (UNS S30403) stainless steel on atmospheric corrosion resistance in urban and marine environments was investigated during 2 months and 7 months of exposure. The surface conditions investigated included as-received, pickled, abraded, and bright-annealed samples. The surfaces were investigated before the exposures, and differences in surface composition, polarization resistance, surface roughness, and wettability were observed between the various surface treatments. During the exposures, all samples decreased in weight. Under the present conditions, the as-received samples showed the best performance in the urban environment, whereas the bright-annealed samples showed the best performance in the marine environment. Different effects of surface treatments on atmospheric corrosion resistance in both environments could be explained best by the resulting differences in passive film composition.
