Abstract
Supersonic spray coating techniques were applied to deposit ceramic and clay particles as films for use in electrical insulation. TiO 2 and Al 2 O 3 ceramics were aerosol-deposited under vacuum while kaolinite, montmorillonite, and bentonite clays were deposited by cold spraying in open air. The electrical resistances of Al 2 O 3 and TiO 2 were ~10 5 and ~10 4 W, respectively. The resistances of kaolinite and montmorillonite were ~10 10 W. Bentonite showed the lowest electrical resistance of ~10 7 W among the clays because of the high cation exchange capacity of the material. The film surface morphologies and mechanical properties in the form of hardness and scratchability were also investigated.
