High temperature corrosion study: experimental techniques

Abstract

Various phenomena occur during the high temperature corrosion of materials: the formation of a scale or of volatile products, the change of the weight and of the size of the samples, the development of mechanical stresses, the variation of the structure and/or the composition of the substrate or of the corrosion products, Specific experimental methods are devoted to the recording of the variations of these different parameters. In this paper some of the most frequently used methods will be described and discussed.
