      abstract     = {Thermally sprayed coatings of Al2O3-TiO2 are extensively
                      used in commercial applications due to their favorable
                      mechanical, electrical or thermal properties. Despite a long
                      history of application, the detailed influence of the
                      feedstock powder is still unclear. Especially, the effect of
                      the compound aluminum titanate (Al2TiO5) on the formation
                      and the properties of the coatings has only crudely been
                      investigated. Accordingly, in this work we systematically
                      examine the morphology, the elemental composition and the
                      phase content of ten distinct commercially available
                      feedstock powders of the common commercial compositions with
                      3, 13 and 40 wt. $\%$ TiO2. Additionally, Al2O3 and TiO2
                      powders are used for comparison. Subsequently, the powder
                      characteristics are related to the resulting microstructure
                      and the properties of Al2O3-TiO2 APS-sprayed coatings, with
                      a special focus on the role of the Al2TiO5. Thereby,
                      improved coating properties can be expected by specifically
                      tailoring the phase composition within the Al2O3-TiO2
                      coating via an improved specification of the feedstock
                      powder.},
