Corrosion by Halogen and Hydrogen Halides

Abstract

Abstract Alloys containing elements that form volatile or low-melting-point halides are susceptible to high-temperature corrosion attack. This chapter explains how to determine whether such phases are likely to form, and the rate at which they occur, based on thermodynamic data and phase stability diagrams. It provides an extensive amount of high-temperature corrosion data for metals and alloys in gaseous environments containing chlorine and hydrogen chloride; fluorine and hydrogen fluoride; bromine and hydrogen bromide; and iodine and hydrogen iodide.
