This chapter discusses three related corrosion mechanisms, galvanic, deposition, and stray-current corrosion, explaining why they occur and how they affect the corrosion process. It includes information on testing and prevention methods along with examples of the type of damage associated with these corrosion mechanisms.

This chapter discusses corrosion prevention methods used with aluminum and its alloys. The methods range from relatively straightforward measures, such as proper handling and storage, to advanced early warning corrosion monitoring systems for military aircraft. The chapter summarizes the basic factors that influence design for corrosion resistance and discusses the use of conversion coatings, organic coatings, porcelain enameling, and electroplating. It also discusses corrosion monitoring methods used in chemical processing and refining industries.

This chapter discusses the development of aluminum, its industry growth, and its modern uses in manufacturing. It begins with the biography of Charles Martin Hall, who invented the process for reducing aluminum from its ore. The evolution of aluminum production from the Pittsburgh Reduction Company to a pilot plant on Smallman Street in Pittsburgh, to a production plant in New Kensington, and to Niagara Falls, New York, is then described. This is followed by a discussion on early aluminum applications and the usage of lower-cost raw materials. The chapter provides information on aluminum production process integrated by Aluminum Company of America (Alcoa) and the numerous technical problems and solutions related to Alcoa's research from World War I to World War II. The aerospace applications for aluminum alloys are also presented. The chapter concludes with a section on aluminum alloys developed by Alcoa.

This chapter addresses the general effects of composition, mechanical treatment, surface treatment, processing, and fabrication operations on the corrosion resistance of aluminum and its alloys. Different types of surface treatments covered include claddings, anodizing, and conversion coatings. The processing steps that can have relatively significant impact on corrosion resistance are homogenization, rolling, extrusion, quenching, aging, and annealing.

This chapter details aluminum products most familiar to consumers including cookware, electronics and TVs, home interiors, luggage and briefcases, and outdoor furniture. Aluminum in art is also discussed.
