      abstract     = {For decades thermally sprayed coatings of Al2O3-13 $wt.\%$
                      TiO2 have been applied in several commercial fields.
                      Nevertheless, the influence of the detailed microstructural
                      characteristics of the feedstock powders on the coating
                      properties have been neglected so far. In this work we have
                      systematically compared different commercial Al2O3-13
                      $wt.\%$ TiO2 feedstock powders with varying aluminum
                      titanate (Al2TiO5) contents and distinct distributions of
                      the metallic elements. The impact of these feedstock powder
                      properties on the microstructure and the mechanical
                      properties of APS coatings was investigated at two different
                      stand-off distances. Different from feedstock powders with
                      higher TiO2 contents, the existence of Al2TiO5 in the 13
                      $wt.\%$ TiO2 powders resulted in an increased hardness in
                      the APS coatings. Overall, the results point at the benefits
                      of an enhanced homogeneity of the metallic elements in
                      Al2O3-13 $wt.\%$ TiO2 feedstock powders.},
