是用来控制金属表面的腐蚀电化学电池的阴极的一种技术。[1]适用于CP的最简单的方法是由金属连接，更容易相互腐蚀的金属保护作为电化学电池阳极。阴极保护系统是用来保护在各种环境下的广泛的金属结构。常见的应用;不锈钢水或燃料管道和储罐，钢桩码头，船舶和船，海上石油平台和陆上油井套管和金属钢筋混凝土建筑物和构筑物
Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell.[1] The simplest method to apply CP is by connecting the metal to be protected with another more easily corroded metal to act as the anode of the electrochemical cell. Cathodic protection systems are used to protect a wide range of metallic structures in various environments. Common applications are; steel water or fuel pipelines and storage tanks; steel pier piles; ships and boats; offshore oil platforms and onshore oil well casings and metal reinforcement bars in concrete buildings and structures
