This chapter covers the friction and wear behaviors of carbon, alloy, and tool steels. It begins a review of commercially available shapes and forms. It then describes the metallurgy and microstructure of various designations and grades of each type of steel and explains how it affects their performance in adhesive and abrasive wear applications and in environments where they are subjected to solid particle, droplet, slurry, and cavitation erosion and fretting damage.

This chapter discusses the processes and procedures involved in tribotesting, the significance of test parameters and conditions, and practical considerations including test metrics and measurements and the interpretation of wear damage. It also describes the different types of erosion tests in use and common approaches for adhesive wear and abrasion testing.

Pitting is the most common corrosion attack on aluminum alloy products. This chapter explains why pitting occurs and how it appears in different types of aluminum. It discusses pitting rates, pitting potentials, and pitting resistance as well as testing and prevention methods. It also discusses the problem of crevice corrosion and how it is influenced by crevice geometry and operating environment. The discussion covers the most common forms of crevice corrosion, including water staining, poultice corrosion, and filiform corrosion, along with related testing and prevention methods.

Failure investigation is an integral part of any design and manufacturing operation, providing critical information to solve manufacturing problems and assist in redesigns. This chapter addresses several aspects of failure investigation, beginning with the challenges of organizing such efforts and the need to define a clear and concise goal, direction, and plan prior to the investigation. It covers the causes of failure and the training and education organizations require to understand and prevent them. The chapter emphasizes the importance of discovering the root cause of failures, and uses examples to explain the factors involved and how to recognize them when the first appear.

This chapter describes the applications with the greatest impact on titanium consumption and global market trends. It explains where, how, and why titanium alloys are used in aerospace, automotive, chemical processing, medical, and military applications as well as power generating equipment, sporting goods, oil and gas production, and marine vessels.
