Über dieses Buch

This SpringerBrief utilizes a surface chemistry/physical chemistry approach toward the study of aqueous corrosion processes. The book starts with a timely and in-depth review of Acid-Base Properties of Surface Oxide Films. Acid-base properties are significant in various surface phenomena such as general and localized corrosion, corrosion inhibition by organic molecules, and the adhesion of organic polymers to oxide-covered metals. This review also discusses the relationship between the two measures of surface charge, the isoelectric point of the oxide film and the potential of zero charge of the oxide-covered metal. Other topics included are capillarity and corrosion, corrosion inhibition, passivity of Fe-Cr and Fe-Cr-Ni alloys, the uptake of chloride Ions and the pitting of aluminum, and the formation of water films on the iron oxide surface.

Chapter 1. Acid-Base Properties of Surface Oxide Films

Abstract

The properties of metal oxide films are important in a number of corrosion phenomena, including passivity and its breakdown, corrosion inhibition by organic molecules, and the adhesion of organic coatings. In addition, the properties of metal oxide films are important in related surface phenomena, such as friction and wear, lubrication, and electrocatalysis. This chapter will consider the acid-base nature of oxide films and the role of acid-base properties in pitting, the adhesion of organic coatings, and corrosion inhibition. Examples and references given here are intended to be illustrative rather than being exhaustive.

Chapter 2. Capillarity and Corrosion

Abstract

The surface of a liquid or solid exhibits the property of surface tension because molecules at the surface of the liquid or solid have fewer neighbors than those in the bulk. This situation leads to a net force perpendicular to the surface plane toward the interior of the liquid (or solid). In the case of solids, the property is called its surface free energy and may depend on the orientation of the solid surface.

Chapter 3. A Recent Model of Passivity for Fe-Cr and Fe-Cr-Ni Alloys

Abstract

Passivity is the reduction in chemical or electrochemical activity of a metal surface due to the formation of a thin protective oxide film tens to hundreds of angstroms thick.

Chapter 4. Uptake of Chloride Ions and the Pitting of Aluminum

Abstract

Aluminum and its alloys undergo pitting in chloride solutions. The protective oxide film present in neutral solutions breaks down in the presence of chloride ions and pitting ensues.

Chapter 5. Formation of Water Films on the Iron Oxide Surface

Abstract

One of the earliest quantitative observations in the field of corrosion science was that there is a critical relative humidity below which atmospheric corrosion is negligible and above which corrosion occurs.

Chapter 6. Corrosion Inhibition by Fluorinated Aliphatic Compounds

Abstract

Using fundamental principles of corrosion inhibition it is possible to “tailor-make” effective corrosion inhibitors. Much useful information is available from the field of surface chemistry.
