Materials, Vol. 11, Pages 1572: The Aerosol Deposition Method: A Modified Aerosol Generation Unit to Improve Coating Quality Materials doi: 10.3390/ma11091572 Authors: Dominik Hanft Philipp Glosse Stefan Denneler Thomas Berthold Marijn Oomen Sandra Kauffmann-Weiss Frederik Weis Wolfgang Häßler Bernhard Holzapfel Ralf Moos Owing to its ability to produce dense thick-films at room temperature directly from a ceramic powder, the Aerosol Deposition Method (AD) possesses a unique feature in ceramics processing. For this technology, the aerosol generation of particles is a decisive part of reliable process control. However, there has only been a small amount of work published addressing this topic. In this work, we compare the aerosolization and deposition behavior of a fluidized bed generator with an aerosol generator with the rotary brush principle. While film properties very much depend on deposition time for the fluidized bed generator, films produced with the brush generator show a constant film profile, and their film thickness correlates with the controllable aerosol concentration and the duration of deposition. This type of aerosol generation may improve the setup towards a more reliable AD process.
