Cyclic and isothermal oxidation

High temperature corrosion in gas mixtures with significant oxygen partial pressure constitute about 90% of all gas degradation processes at high temperature. These high temperature oxidation processes can occur by an alternating increase and decrease of temperature or by maintaining the temperature constant throughout the whole experiment. In the first case, cyclic oxidation, the conditions are more complex since the oxidation process is combined also with additional mechanical stresses that the oxide experiences at the interface with the base metal. In the second case, stable isothermal conditions are maintained throughout the experiment. Research has been performed on steel and superalloys with and without surface modifications and the effect of specific protective coatings on oxidation resistance has been analyzed.
