Corrosion can be defined as a chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties. This chapter describes the effects and economic impact of corrosion in major industrial plants. The emphasis in this chapter, as well as in other chapters in this book, is on aqueous corrosion, or corrosion in environments where water is present. The chapter describes the classification of various forms of corrosion based on the nature of the corrodent, mechanism of corrosion, and appearance of the corroded metal. It discusses five primary methods of corrosion control, namely, material selection, coatings, inhibitors, cathodic protection, and design. Examples of the opportunities in corrosion control and the means to implement a program to capitalize on those opportunities are presented in a table. The chapter concludes with varied sources of information pertaining to corrosion and corrosion prevention.

This chapter discusses design and certification considerations, including materials and process selection, the building block approach to certification, design allowables, and design guidelines. It also includes information on damage tolerance and environmental sensitivity.

This chapter focuses on high-pressure cold spray applications pertaining to repair and refurbishment in the aerospace, oil and gas, and power-generation industries, the last specifically involving repair of gas turbine components. Advantages of cold spray coating in the repair and refurbishment of structural engineering components are also discussed.

This article describes the repair of weld defects and failed structures. It provides information on three factors that must first be considered before attempting a repair, namely material weldability, nature of the failure that prompted the repair, and involvement of any code requirements. The article discusses the processes involved in welding process selection and the methods of preparing base metal for repair welding. It presents the guidelines for weld repairs of various ferrous (carbon steels, cast irons, and stainless steels) and nonferrous (for example, titanium) base metals.

This chapter discusses the functions of surface treatments important for stainless steel, namely the removal of oxide scale and cleaning, brightening, and coloring of the stainless surface. Details on the main methods of producing aesthetic surface finishes are also provided.

This chapter describes the making of iconic structures such as the Chrysler Building. It also describes the discoveries of the Nirosta (18-8) stainless steel that was used for the construction of the Chrysler Building. The chapter presents William Van Alen's description of 18-8 stainless steel for the Chrysler Building. It provides information on the opening ceremonies for the Chrysler Building, Van Alen's vision, and the exterior of the building.

From canoes to catamarans, aluminum is used for a variety of marine applications. Fishing boats, pontoon boats, ferries, oceangoing liners, and military vessels all benefit from the weight savings, corrosion resistance, and weldability of aluminum products. This chapter shows examples of aluminum boat construction. It presents important issues with the 5xxx shipbuilding alloys, such as corrosion. The chapter also presents the benefits of using aluminum in marine applications.

This chapter discusses the maintenance needs of major components in induction heat-treating systems, including power supplies, heat stations, capacitors, high-frequency output stages, induction coils, water systems, quench systems, and fixturing.

Fracture control can be defined as a concerted effort to maintain operating safety without catastrophic failure by fracture. It requires an understanding of how cracks affect structural integrity and strength and the time that a crack can grow before it exceeds permissible size. The chapter describes some of methods used to determine maximum permissible crack size and predict growth rates. It explains how the information can then be used to control fractures through periodic inspection, fail-safe features, mandated retirement, and proof testing. It presents a number of fracture control plans optimized for different circumstances, examines the damage tolerance requirements used by different industries, and discusses various approaches for fatigue design.

This chapter discusses the tooling used for autoclave curing, one of the most common composite fabrication processes. The discussion covers curing practices, material selection factors, and design challenges associated with thermal expansion, tool shrinkage, part complexity, and heating and cooling rates. The chapter also includes best practices and recommendations for toolmaking and assembly.

This article presents a simple cost/pricing system that is reasonably accurate and could easily be recalculated if the yearly cost of any of the basic cost components change. Using the example of a commercial heat treating facility, the operational details are categorized as atmosphere processes, induction processes, aluminum processes, high-heat processes, and secondary processes. For the purpose of calculating the heat treatment processing cost per hour and the selling price for a piece of equipment, the costs are separated into direct costs, allocated costs, capitalized cost, and general and administrative costs. The article discusses the techniques involved in allocating costs to the group of equipment, and presents a description on the cost analysis of endothermic gas.

This chapter discusses the work of a famous stainless steel pioneer, Edward G. Budd. The discussion covers his early years, his automobile body business, the arrival of novel kind of stainless steel in America, Earl Ragsdale's shot weld patent, the world's first stainless steel airplane, the world's first stainless steel rubber-tired train, the Flying Yankee, the Mark Twain Zephyr, the development of the Budd Company in the war years and postwar years, and a review of the Budd Era.

Pattern equipment is the tooling utilized to form the mold cavity of a casting. This chapter first discusses the following factors that should be considered for determining the type of pattern equipment: number of castings to be produced, mold processes to be employed, dimensional tolerances required, casting design, and pattern cost. It also discusses the factors that should be considered when engineering a pattern. The chapter then presents the types of materials used for pattern construction. It provides an overview of patternmaker's shrinkage allowance. Finally, the chapter presents the factors that govern the space requirements for pattern storage.

This chapter provides an introduction to induction soldering. It also illustrates the classification of the different soldering processes according to the heat source, as described in the German standard, Soldering: Categorization of Processes According to Energy Sources, Process Descriptions.

Cold spray is a process technology that, for the first time, enables the rapid deposition of a wide range of metals and some other materials in the solid state at temperatures far below their melting points. This chapter provides an overview of the processes involved in cold spray process technologies, namely high-pressure cold spray (HPCS) and low-pressure cold spray (LPCS), explaining differences of LPCS from HPCS. It summarizes the historical background of the cold spray process. The growing international interest in the cold spray process from the early 2000s is also reviewed.
