摘要
总结了近几年来我国在大气腐蚀方面的研究现状和进展,包括国产、常用、量大、面广的4大类材料在我国9类主要典型大气环境下的腐蚀数据积累;各类典型材料在典型环境下的大气腐蚀行为规律;大气环境因素对材料大气腐蚀的影响;碳钢、低合金钢大气腐蚀行为预测,特别是根据8年试验结果所总结出的大气腐蚀速度与试验时间之间具有幂函数关系的基础上,又进一步建立了腐蚀速度与合金元素之间的数学模型关系;探讨了采用ACM技术评估大气腐蚀严酷性;初步建立了大气腐蚀数据库,并正进一步采用计算机发展网络查询服务系统,实现科学数据共享。经20余年之研究,撰写了并出版中国材料自然环境腐蚀专著中大气腐蚀篇,还研制和生产了经济耐候钢。
Development status of atmospheric corrosion in China in recent years was summarized. It included corrosion data accumulation of 4 kinds of materials in 9 kinds of typical atmospheric environments in China and atmospheric environment＇s effect on materials atmospheric corrosion. The materials＇ characteristics were home made, commonly used, plentiful and forgoing. Prediction for atmospheric corrosion behavior of carbon steels and low alloy steels was studied. Especially power function relationship between atmospheric corrosion and corrosion time was established based on testing results of 8 years. Furthermore, mathematic mode on relationship between alloy element and corrosion depth was established. Evaluation of atmospheric corrosion astringency by adopting of ACM technology was discussed. Atmospheric corrosion database was established. Based on this, scientific data sharing was realized by developing network query technology. After more than 20 years＇ study, monograph, titled Material Corrosion in Natural Environment in China-Atmospheric Corrosion, was published and economic weathering steels was developed.
