钢铁材料有很多优点,在国民经济各部门中广泛应用,至今仍没有其他材料可以完全替代钢材,其仍然是21世纪的主要结构用材。但是,钢铁材料也存在一个最大缺点——极易腐蚀。每年,世界金属因腐蚀要造成的损失大约占钢产量的5%～10%。为减少因腐蚀造成的钢材损失,近百年来,世界科学家进行了大量的研究和实验,找到了不少减缓钢材腐蚀的办法。通过对各种方法的技术经济对比后,发现采用钢材表面进行防腐处理是防止钢材腐蚀最有效最经济的
Steel has many advantages and is widely used in various sectors of the national economy. To date, there are no other materials that completely replace steel. It is still the main timber for the 21st century. However, there is one of the biggest drawbacks of steel materials - extremely corrosion-resistant. Each year, the loss caused by corrosion of the world’s metal accounts for about 5% to 10% of the steel output. In order to reduce the steel loss caused by corrosion, a great deal of research and experiments have been carried out by scientists all over the world in the past hundred years, and many ways to reduce the corrosion of steel have been found. Through the technical and economic comparison of various methods, we found that the use of steel surface anti-corrosion treatment is to prevent steel corrosion is the most effective and most economical
