In this paper, the processes as well as the first results regarding the economic efficiency and plasma fuel properties of nanostructured zirconium oxide powder particles are explained. The paper evaluates values for porosity, hardness, roughness, and crystallite size. In addition, both the morphology of the powder particles and the spatter are analyzed by SEM, and cross sections of the coatings are observed using optical microscopy. These results are compared to coatings made from a commercially available yttria stabilized zirconia powder. Paper includes a German-language abstract.
