摘　　要：本文简要阐明了为什么金属腐蚀主要以电化学腐蚀的形式出现,剖析了腐蚀过程电化学动力学参数的物理意义,以及金属腐蚀的防护原理、常用的腐蚀防护方法乃至腐蚀过程的一些特殊应用.In celebration of the International Year of Chemistry in 2011,this paper explains why corrosion processes are usually electrochemical in nature,describes the significance of electrochemical kinetic parameters in corrosion processes,and briefly introduces the principles of corrosion protection.The most commonly used corrosion protection methods and some special applications in corrosion processes are highlighted.The important engineering application of corrosion and corrosion protection in gasoline transportation from western to eastern in China is illustrated to demonstrate the key achievements in development of national economics.
