Abstract in another language

The Aerosol Deposition Method (ADM) is a coating process which has the remarkable advantage of enabling the manufacture of dense layers at room-temperature directly from ceramic powder. In this method, ceramic particles are dispersed with a gas to form an aerosol, which is accelerated onto a substrate to form dense layers. The aim of this work was to investigate how the process parameters affect the optical properties (e.g. transmittance) of aluminum oxide and yttrium aluminum garnet layers on glass substrates. As-deposited layers were characterized including microstructure and phase analysis as well as optical measurements. For aluminum oxide dense and crack-free layers with thicknesses up to 50 μm were obtained, whereas, yttrium aluminum garnet layers exhibited lower density and integrity. Layer characteristics and deposition procedures are discussed with respect to the entire processing procedure to derive a deeper understanding of the intrinsic deposition mechanisms and critical parameters.
