    2 Basic Concepts in Corrosion The formation of a corrosion cell is essential for corrosion to take place. A corrosion cell is essentially comprised of the following four components: anode, cathode, electrolyte, and metallic path. All metals have characteristic electrode potentials. They can be measured with respect to a standard electrode, such as Standard Hydrogen Electrode (SHE). Corrosion cell: anode, cathode, electrolyte, and metallic path

    3 Types of Corrosion: Materials and Environments This chapter discusses various forms of corrosion with remedial measures. Some of them are: uniform corrosion, galvanic corrosion, dezincfication, crevice, and pitting corrosion. In the chapter, each form of corrosion is discussed by definition, environment, mechanism, and methods of prevention. The factors affecting corrosion are also discussed in the chapter. To realize various forms of corrosion by definition, environment and mechanism and then to study the methods of prevention.

    10 Cathodic Protection The chapter illustrates the simple principle of cathodic protection. On application of an external current, the difference of potential between the cathodes and anodes on the structure decreases. It also discusses factors leading to corrosion of underground metallic structures. It discusses the various components of galvanic systems, impressed current systems, AC/DC systems, and a rectifier. Some commercial specifications and details of zinc anodes are appended to this chapter.

    11 Corrosion Control by Inhibition The practice of corrosion prevention by adding substances, which can significantly retard corrosion when added in small amounts, is called inhibition.There are two major classes of inhibitors: inorganic and organic. Inhibitors can also be classified on the basis of their functions. The effect of inhibitor on the metal/electrolyte system can be successfully evaluated by polarization diagrams. There are three well-known inhibitor application techniques—continuous injection, batch treatment, and squeeze treatment.

    12 Coatings Coatings can be classified in the following categories according to their corrosion resistance: barrier coatings, conversion coatings, anodic coatings, and cathodic coatings. Miscellaneous coatings include glass coatings, porcelain coatings, and high-temperature coatings. This chapter discusses coating processes. Coating and paint technologies adapt to environmental requirements. The development of water-borne coatings and solvent-free coatings signify new health and safety trends in coating technology.

    13 Corrosion Prevention by Design This chapter discusses how corrosion can be prevented by adopting good design practices. Selection of a corrosion-resistant material for the environment is a prerequisite to a good design. Material and design are both complimentary to each other and neither of the two can be ignored. This chapter discusses how corrosion can be prevented by adopting good design practices. Selection of a corrosion-resistant material for the environment is a prerequisite to a good design.

    14 Materials Selection for Corrosive Environment The selection of appropriate materials in a given environment is a key factor for corrosion control strategy. The material selected has to meet the criteria for mechanical strength, corrosion, and erosion resistance for specific service conditions. The selection of appropriate materials in a given environment is a key factor for corrosion control strategy. This chapter teaches the knowledge of corrosion resistance of a material in a given environment.
