分析几种典型的碳钢、耐候钢在西部环境暴露的腐蚀数据,并与东部的环境腐蚀数据进行对比,同时利用新试验站点的环境数据及新钢种的腐蚀数据,验证了“九五”期间建立的大气腐蚀预测模型.结果表明,气候干燥、污染低的拉萨、敦煌,各种钢的腐蚀轻微,远远低于东部试验点,而库尔勒由于污染较重,各种钢的腐蚀较重;东部试验站点新钢种的腐蚀基本符合大气腐蚀预测模型,而西部试验站点新钢种的腐蚀与大气腐蚀预测模型偏差较大.
The corrosion data of several typical carbon steel and weathering steel exposed in the western environment were analyzed and compared with the data of environmental corrosion in the eastern part of China. At the same time, the environmental data of the new experimental site and the corrosion data of the new steel type were used to verify the “ ”.The results show that the corrosion of all kinds of steel in Lhasa and Dunhuang, which has a dry climate and low pollution, is slightly lower than that in the eastern part of the country, and Korla, due to the heavy pollution, all kinds of steel corrosion Heavier. The corrosion of the new steel species in the eastern experimental site basically conforms to the atmospheric corrosion prediction model, while the deviation of the new steel species in the western experimental site from the atmospheric corrosion prediction model is large.
