      abstract     = {In high‐temperature combustion atmospheres,
                      well‐adhering environmental barrier coatings (EBCs) are
                      required to protect the underlying ceramic matrix composites
                      (CMCs) from corrosion. Herein the adhesion mechanisms of
                      three different coatings produced by atmospheric plasma
                      spraying (APS) on an Al2O3/Al2O3‐CMC are investigated. In
                      particular, the influence of surface structuring by laser
                      ablation prior to coating production is investigated. Y2O3,
                      yttria‐stabilized zirconia (YSZ), and Gd2Zr2O7 are chosen
                      as potential EBCs. The coating adhesion on CMC‐substrates
                      with and without surface structuring is analyzed by furnace
                      cycling, pull‐adhesion tests, and burner‐rig tests with
                      gradient. Special interest is paid to the interactions at
                      the coating–substrate interface before and after heat
                      treatment and their effect on the coating adhesion and
                      lifetime. Two different adhesion mechanisms are found:
                      adhesion promoted by chemical reaction and adhesion promoted
                      by mechanical interlocking.},
