      abstract     = {Thermal barrier coatings (TBCs) based on yttria-stabilized
                      zirconia (YSZ) were deposited by Atmospheric Plasma Spray
                      (APS) on highly dense and pure Cr2AlC substrates. The
                      Cr2AlC/YSZ systems were tested under thermal cycling
                      conditions at temperatures between 1100 and 1300 °C
                      testing up to 500 h. The response of the system was
                      excellent due to the strong adhesion between the substrate
                      and the coating, and the formation of an outer and
                      protective layer based on α-Al2O3. The oxide scale is
                      formed due to the diffusion of Al atoms from the crystal
                      structure of the Cr2AlC, followed by the reaction with
                      oxygen in the air. The thickness of the oxide scale was 8.9,
                      17.6 and 39.7 μm at 1100, 1200 and 1300 °C,
                      respectively, which is rather thick in comparison with the
                      classical superalloy/TBC systems. Cr2AlC/YSZ systems
                      survived without any damage under the severe cycling
                      conditions at 1100 and 1200 °C due to the protective
                      oxide scale layer and the sufficient thermal expansion match
                      between the Cr2AlC, YSZ and α-Al2O3. At 1300 °C and
                      after 268 h of cycling conditions, the system failed due
                      to the formation of a porous carbide layer underneath of the
                      oxide scale. The results are rather promising and confirm
                      the potential of the MAX phases to operate under long term
                      applications of high temperature and oxidizing
                      environments.},
