Abstract

The examination of products of aqueous and non aqueous corrosion is carried out to obtain information about one of a combination of aspects such as composition, hardness, stress level, adhesion to basis metal and other mechanical properties (figure 1). A number of techniques are avialable to investigate corrosion products and some of these techniques have found greater application with products of aqueous corrosion and some with products of gaseous corrosion. This paper presents the technqiues available for obtaining information about the various aspects mentioned above and discusses the main characteristics, nature of data obtainable, advantages and limitations of some of the less know techniques.

Abstract

Corrosion is the degradation of metals by chemical or electrochemical reaction with loss of their physical properties in specific areas or overall. Every year in industrialised countries the losses due to corrosion are enormous — roughly about 3.5 to 4.2% of a country's GDP, and running into billions of dollars. A significant part of these losses can be avoided by putting into practice existing corrosion control measures in a systematic manner.
