国家经济建设、国防建设和高新技术的发展都离不开材料,而材料总是在一定环境中使用,在环境作用下都存在腐蚀或老化问题。材料腐蚀不仅给国家带来重大的经济损失和大量资源与能源的消耗,还会给装备、建筑物及人身安全带来威胁。我国由于腐蚀引起的经济损失约达5%,而其中自然环境腐蚀导致的损失占总损失80%以上,有关研究已列为国家建设中一项必须长期坚持的重要基础性工作,积累的腐蚀数据是国家基本建设特别是重大工程建设中合理选
National economic development, national defense construction and the development of new and high technology are inseparable from the material, and the material is always used in a certain environment, under the action of the environment there is the problem of corrosion or aging. Material corrosion not only brings about significant economic losses to the country and consumption of large amounts of resources and energy, but also poses threats to the equipment, buildings and personal safety. The economic loss in our country due to corrosion is about 5%, of which the loss caused by natural environment corrosion accounts for more than 80% of the total loss. The research has been listed as an important basic work which must be adhered to for a long time in national construction and the accumulated corrosion data It is a reasonable election for national capital construction, especially for major construction projects
