This paper investigates the microstructure, bond adhesion, and high temperature and thermal fatigue performance of plasma-sprayed chromium carbide, nickel-chromium coatings after continuous exposure at high temperature inside a combustion chamber that simulates the extreme conditions existing in different industrial applications. Experiments on high temperature behavior under oxidative and neutral atmospheres and thermal fatigue tests are carried out in a test combustion chamber. Finally, the adhesion between the substrate and the coating layer is assessed using tensile tests. The paper discusses the results with special consideration of the microstructure development through the heat treatment. Paper includes a German-language abstract.
