中文摘要：
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.
英文摘要：
Atmospheric corrosion data of several typical carbon steels and weathering steels exposed in Western and Eastern areas of China were collected and analyzed with the aim of examing the atmospheric corrosion model proposed on the basis of corrosion data gained from exposure sites of the national network located at Eastern China until the end of last century. The results showed in general that the corrosion amount of steels exposed in exposure sites at the Western China such as Lasa and Dunhuang was far less than those at the Eastern China.However, the steels exposed in the site at Kuerle exhibited rather severe corrosion due to environmental pollution there.Therefore,the existed corrosion model is more suitable to predict the corrosion behavior of steels in harsh corrosive environments rather than that in less corrosive ones.
