Carbon dioxide is one of the possible working media for future advanced technologies in the power industry. Its use is possible in the supercritical state as a cooling medium in the nuclear power industry, as an extraction solvent, in the combustion of fossil fuels, in concentrating solar systems, or in CCS(Carbon Capture and Storage) processes. Important factors for these technologies will be the durability and compatibility of the construction materials in CO2 and flue gas environments at high temperatures. This work describes the behavior of nickel-based alloys in a model flue gas environment and the condition of the surface layers after this exposition. The exposed samples were analyzed by XPS and by EDS detector on an electron scanning microscope (SEM). According to the exposure results, the nickel alloy samples are suitable for the model flue gas environment, and their suitability will be verified at 900 °C in further experiments. This project TK01030089 was co-financed with the state support of the Technology Agency of the Czech Republic within the Théta Programme.
