众所周知,大气腐蚀是人们生活中常见的一种自然现象,起因复杂,后果严重。据世界各国有关统计,每年冶炼所得钢材的十分之一或更多一些因其腐蚀破坏而废弃不能用。苏联达40％。美国每年因大气腐蚀损失约20亿美元,其它国家的经济损失也甚大。大气腐蚀给国民经济带来的严重后果,使人们必须重视研究。目前国内外为了防止钢材的大气腐蚀,都在积极采取各种有效措施。上海市科委、上海市冶金局组织了上海新沪钢铁厂、上海市第一钢铁厂、上海市建筑
As we all know, atmospheric corrosion is a common natural phenomenon in people’s lives, with complex causes and serious consequences. According to relevant statistics of various countries in the world, one-tenth or more of the smelted steel obtained each year cannot be used because of its corrosion and destruction. The Soviet Union reached 40%. Every year, the United States loses about 2 billion U.S. dollars due to atmospheric corrosion, and the economic losses of other countries are also very large. The serious consequences of atmospheric corrosion on the national economy make people must pay attention to research. At present, in order to prevent the atmospheric corrosion of steel, both at home and abroad are actively taking various effective measures.
