课程名称：保护世界：腐蚀科学与工程简介 课程概述：本课程由曼彻斯特大学的Corrosion@Manchester团队与阿克苏诺贝尔公司合作开设。无论是遭遇生锈的汽车车身、漏水的管道、褪色的银器，还是铜屋顶的绿色铜绿，这些都是腐蚀现象的表现。课程旨在讲述金属腐蚀的原因、环境后果、腐蚀的成本以及如何控制腐蚀。该课程适合学生、家庭、教师、专业人士及其他有兴趣的人士，帮助他们理解腐蚀以及腐蚀控制的复杂世界。 课程目标是介绍腐蚀及其控制的基本知识，尽管深入理解腐蚀科学需要材料科学、电化学和物理学的知识，但该课程不需要广泛的背景知识，适合所有水平的学习者。它反映了曼彻斯特大学腐蚀控制工程课程的元素，供最后一年本科生和硕士研究生使用，也可作为学习的补充资源。 课程大纲： 第一周：腐蚀原理 在这一周，我们将介绍腐蚀的科学和工程概念。内容包括腐蚀的定义、成本、腐蚀工程师的作用，八种腐蚀类型的实例及其与工程设计的关系，材料属性及如何理解金属（锌）的腐蚀，腐蚀的经济与社会后果，以及电化学腐蚀的科学，最后探讨曼彻斯特腐蚀博物馆的腐蚀失效案例。 第二周：阴极保护 本周将讨论阴极保护的工作原理及其应用。我们将讨论阴极保护的基本原则并将其与之前学过的概念结合，探讨阴极保护系统的设计标准和现有结构的保护需求，以及混凝土结构的阴极保护方法，确保保护钢筋的质量。 第三周：表面工程 本周将介绍表面工程，包括表面工程的定义、表面保护涂层的作用及设计标准、不同的表面工程技术，以及涂层在工业抗腐蚀中的应用、性能和失效机制。 第四周：油田腐蚀及控制 第四周重点介绍油田腐蚀科学与工程。您将学习与腐蚀现象相关的内容以及其他降解过程，探索减少设施降解的方法，涉及油田设备类型、酸性/碱性腐蚀、海水腐蚀、结垢、侵蚀、腐蚀预测、抑制和管理等主题。 此次课程为参与者提供了一个全面的腐蚀科学与技术的基础，有助于更好地理解和应对相关问题。
Name:Week 1: Principles of Corrosion
Description:In Week 1 we show you the scientific and engineering concepts that are important to an understanding of corrosion in practise. Section 1 provides a brief outline of what corrosion is, how much it costs and how corrosion engineers can help. Section 2 lists, with examples, the eight types of corrosion and shows the important of good engineering design on corrosion control. Section 3 focuses on materials properties and introduces how the corrosion of metals (zinc) may be understood. Section 4 looks directly at the economic and social consequences of corrosion. In section 5 we pick up the pace to focus on the science of electrochemical corrosion. Finally, in section 6, we wind up with a selection of corrosion failures chosen from the Corrosion@Manchester museum.
Name:Week 2: Cathodic Protection
Description:This week, will discuss how cathodic protection works and how it can be applied in practice to protect metallic structures.Firstly, we’ll discuss some of the basic principles behind cathodic protection, and we will see how some of the concepts you have learned in the other units are applied in a cathodic protection scenario.Subsequently, we’ll discuss some aspects related to the design of cathodic protection systems, such as for example the criteria that have to be satisfied to achieve a good level of corrosion protection, or the method used to assess the requirements for an existing structure in terms of cathodic protection current.Finally, we’ll touch on cathodic protection of reinforced concrete structures, discussing the factors that contribute to good concrete quality and discussing how we can protect the reinforcement steel bars by using cathodic protection.This week’s material is split into 6 sessions. Each session lasts approximately 20 minutes; at the end of each session, there will be a quiz to test your knowledge.
Name:Week 3: Surface Engineering
Description:In Week 3, we will introduce Surface Engineering. The learning materials for this week are organised into five sections. Throughout the week, we will clarify what surface engineering is and why surfaces are important. We will look into how coatings protect surfaces from corrosion and will discuss coating design criteria. We will also consider various Surface Engineering techniques. Finally, we will turn our attention to industrial applications of coatings for corrosion protection, coating performance and failure mechanisms.
Name:Week 4: Oilfield Corrosion and Control
Description:Week 4 provides an introduction to oilfield corrosion science and engineering. You will learn about pertinent corrosion phenomena, as well as other degradation processes, along with approaches to minimise facility degradation. Specific topics include: types of oilfield equipment; sweet/sour corrosion; seawater corrosion; scaling; erosion; corrosion prediction; corrosion inhibition; corrosion management.

If you have ever encountered rusty car bodies, leaking pipes, tarnished silverware or the green patina of a copper roof then you have experienced corrosion in action. This course, from the Corrosion@Manchester team in collaboration with AkzoNobel, will teach you why metals corrode, what the environmental consequences are, how much corrosion costs and how corrosion can be controlled. It is designed for students, householders, teachers, professionals and anyone in-between. The aim of the course is to introduce the complex world of corrosion and corrosion control. While a full appreciation of corrosion science involves elements of materials science, electrochemistry and physics while corrosion engineering requires a practical knowledge of corrosion failures and engineering design this course does not need an extensive background knowledge. The course mirrors elements of the Corrosion Control Engineering teaching programme at The University of Manchester for final-year undergraduates and masters-level postgraduates and is used as a supplementary learning resource by our students.
