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.
