ABSTRACT:
A plasma sprayed TiO2coating is used to remove effluents produced during an electrical charging step using a corona charging device. The plasma spray allows for the application of TiO2ceramic to an aluminum dicorotron housing. Plasma spray also increases the electrical conductivity of the TiO2(which is necessary for the dicorotron operation). Plasma sprayed coatings are also porous which aids in the capture and reduction of effluents.
