钢铁是最重要的工程材料,镀锌是保护钢铁腐蚀最经济有效的方法。本文将根据钢在世界范围内的各种自然环境中的腐蚀速率的统计结果,讨论锌镀层在这些环境中的保护效益和新型镀层的发展潜力,介绍目前国际钢上在开发耐蚀性能,使用性能和经济效率更好的新型的镀层上的发展动向。更耐蚀的镀层系统可以使钢铁产品除了在使用的最多的大气环境里以外,能够在其它更多的环境里使用,比如土、水、水泥,或含有化学药品的特殊环境里。有效评判腐蚀性能的加速腐蚀试验的开发和使用以及对各种腐蚀现象的深入理解将对镀锌钢材的进一步应用和新镀层系统的开发有特别的意义。
Steel is the most important engineering material, and galvanizing is the most cost-effective way to protect steel from corrosion. Based on the statistical results of corrosion rates of steel in various natural environments around the world, this paper discusses the protective benefits of zinc coatings in these environments and the potential of new coatings. The current international steel corrosion resistance in the development, use Performance and cost-effective new coatings on the development trend. The more corrosion-resistant coating systems allow steel products to be used in more environments than just the most atmospheric environments, such as soil, water, cement, or special environments containing chemicals. The development and use of accelerated corrosion tests that effectively evaluate corrosion performance, as well as a thorough understanding of various corrosion phenomena, will be of particular interest for the further application of galvanized steel and the development of new plating systems.
