**课程名称：** 阴极保护腐蚀控制系统 (Cathodic Protection Corrosion Control System) **课程概述：** 本课程专注于讨论地下、海上、水下及其他暴露在电解质中的金属结构所面临的重要问题——腐蚀。若不加以控制，腐蚀将带来高昂的维修或设备更换成本，甚至因环境破坏、人员伤亡而造成更大的损失。 课程面向阴极保护现场技术人员（同时也适用于腐蚀工程人员），旨在帮助学员建立对腐蚀机理的良好基础理解，并掌握地下设施发生腐蚀的各种条件。课程的核心在于阐述如何通过应用阴极保护技术来控制金属腐蚀。 **阴极保护的核心原理：** 阴极保护是一种腐蚀控制技术，通过将待保护的金属表面置于电化学电池的阴极侧来实现。最直接的方法是将待保护金属与更容易腐蚀的金属连接，使其充当电化学电池的阳极。理论上，阴极保护可用于保护任何与大量电解质接触的金属结构。然而，在实际应用中，它最常用于保护埋藏在土壤或浸泡在水中的钢结构。 **应用领域：** 阴极保护系统广泛应用于各种环境下的多种金属结构，包括但不限于： * 水管和燃料管道 * 储罐 * 船舶 * 海上石油平台 * 油井套管等。 本课程将深入讲解阴极保护的基本原理，并介绍该领域的最新进展。
Corrosion is one of the most important problems encountered by the owners and operators of underground, offshore, submerged and other metallic structures exposed to an electrolyte. If corrosion is not controlled, it can lead to large costs in repairs or facility replacement. Even greater costs can be incurred from environmental damage, injuries and fatalities.Corrosion control personnel must have a good basic understanding of corrosion mechanisms. They also need to know the various conditions under which corrosion can occur on underground facilities. In this course, we will focus on the control of metallic corrosion by applying cathodic protection. This course was developed for cathodic protection field technicians, although this knowledge is also needed by corrosion engineering personnel. Cathodic protection (CP) is a corrosion-control technology that involves making a metal surface the cathodic side of an electrochemical cell. Connecting the metal to be protected with a more readily corroded metal to act as the anode of the electrochemical cell is the easiest way to apply CP. In theory, cathodic protection can be used to protect any metallic structure in contact with a bulk electrolyte. However, it is most commonly used to protect steel structures buried in soil or submerged in water in practice. Cathodic protection systems protect a variety of metallic structures in various situations. The most prevalent are water and fuel pipelines, storage tanks, ships and boats, offshore oil platforms, oil well casings, and other applications. This chapter will go through the fundamental principles of cathodic protection and current advancements in the field.
