摘　　要：对陆上风力发电设备中常用的碳钢及各种涂层进行了盐雾试验研究,通过表面观察及电化学阻抗谱测量评价其耐海洋大气腐蚀性。结果显示:碳钢及试验中的镀锌试片、铁红环氧防锈漆试片耐盐雾腐蚀性均较差;含灰色醇酸漆的镀锌试片具有相对较高的耐蚀性能,但试验过程中出现不同程度的脱落,亦不能承受长时间的盐雾腐蚀。The corrosion behavior of the carbon steel and various anti-corrosion coatings, which are used abundantly in land wind power equipment, were tested by salt spray tests, and their corrosion resistance to oceanic atmosphere was also evaluated by surface observation and electrochemical impedance spectroscopy （EIS）. The experimental results show that the corrosion resistance of the carbon steel, zinc-plating samples, and epoxy antirust paint samples are all weak. The zinc- plating sample covered with gray alkyd enamel has better anti-corrosion performance than others, but it is also not an ideal material for offshore wind power equipment since it desquamates during the test.
