This chapter provides a detailed account of crevice corrosion of metals. It begins by describing various critical factors influencing crevice corrosion. This is followed by a section presenting selected examples of crevice corrosion of stainless steel, nickel alloys, aluminum alloys, and titanium alloys in different environments. Methods that have been developed for differentiating and ranking the resistance of alloys toward crevice corrosion are then reviewed. The chapter concludes by discussing various strategies for the prevention of crevice corrosion, namely design awareness, use of inhibitors, and potential control methods.
