Electrode Potential / Temperature Diagrams and Their Application to High Temperature Corrosion

  • M. Pourbaix


Diagrams set up as a function of an electrode potential and temperature allow to represent the influence of temperature, pressure and composition of a gaseous phase on the conditions of stability and metastability of all substances which may exist in a given chemical and electrochemical system. They may be helpful for predicting the conditions of high temperature corrosion of metals and alloys. They may also be a valuable guide for experimental research and technical control.

Examples are given concerning the high temperature behaviour of iron, aluminum, chromium, silicon and carbon, as well as of inorganic coatings, in atmospheres containing oxygen and/or sulphur derivates.
