HIGH TEMPERATURE CORROSION

Two areas of interest in high temperature corrosion are:

1. the degradation of materials by molten salts, in which the aim of the research is to identify the fundamental chemical or electrochemical reactions and the transport processes that are involved in the degradation process, and
2. the evolution of stresses that develop in oxide scales as a result of scale growth processes and of cooling and heating.

Applications include hot corrosion of metals and alloys and dissolution of oxides in molten carbonate salts. Oxide stresses are being examined by theoretical and modeling studies, measurements of stresses with high temperature x-ray diffraction, and in-situ measurements of scale fracture using acoustic emission.
