Aerosol deposition (AD) is a revolutionary way of producing thick ceramic films using
a kinetic particle spray. The deposition takes place at room temperature, occurs
at a very rapid rate compared to other techniques, and can be done on virtually any
substrate material. The resultant ceramic coating is nano-crystalline and is fully
dense. Tremendous potential exists for sensing, catalytic, energy and tribology
related applications. Fuierer’s group is leading this technology in the United States,
while his German colleagues at the University of Bayreuth are leaders in Europe.
Together, they have designed new gas sensors and sensing materials. Fuierer’s group
is now focused on depositing functional ceramics of various type (e.g. Al2O3, TiO2, NiO, LiCoO3, MoS2, Si) and exploring additional application areas for these unique films. Also of
interest is the multi-scale surface roughness and intrinsic stress state of the coatings.
