Abstract

The Powder Aerosol Deposition (PAD) is a novel coating technique for producing dense films from a wide range of ceramic materials. Since the deposition takes part at room temperature, the coating of heat sensitive substrates such as polymers is possible. During the deposition process, ceramic particles impact onto the substrate surface and break into nanocrystalline fragments. However, this mechanism of film formation may cause a decrease in the functional properties of the ceramics, such as the electrical conductivity. Thermal annealing enables to restore the functional properties. This posttreatment is usually carried out by time and energy intensive oven processes. A novel approach utilizes high power light emitting diodes (LED) for the annealing process. The garnet-type lithium ion conductor Al0.2Li6.025La3Zr1.625Ta0.375O12 (ALLZTO) was synthesized and deposited using PAD. The electrical conductivity of the PAD layers was increased by more than a decade in less than two minutes under LED irradiation. Screen-printed temperature sensors were employed to determine the temperature evolvement during the posttreatment process.
