High temperature oxidation of metallic alloys is a complex phenomenon involving multiple processes, e.g., solid state diffusion, creation and movement of defects in the material, arrival of gaseous species at the surface of the material being oxidized, etc. Simulating high temperature service environments in the laboratory enables the development of insights into the formation and stability of oxide films on metallic substrates. In this research project, we are aiming to build a cyclic oxidation setup that will enable us to subject metallic alloys with and without protective coatings to temperatures on the order of 1200C down to room temperature and back.. Typical cycles are one hour exposures at the elevated temperature followed by air cooling to room temperature, holding for about 15 minutes and subsequently exposing the sample to the high temperature for an hour, etc. These high and low temperature cycles may number in the hundreds or thousands. We will discuss current designs of cyclic oxidation setups and highlight critical features. This will be followed by videos and discussion of different aspects of our current design implementation. Critical issues relative to further development will be discussed.
