ABSTRACT:
An element in a corona generating device having at least one conductive corona discharge electrode for depositing negative charge on an imaging surface in an electrostatographic imaging apparatus, the element being capable of adsorbing nitrogen oxide species generated when said corona generating device is energized and capable of desorbing nitrogen oxide species when the corona generating device is not energized, the element having an adhesion, promoting surface reclaimed from prior use in a similar capacity by immersion in an alkaline ultrasonic bath where the cavitation action of the bath is sufficient to remove any binder thereon and any metal, metallic compound and other solid particles as solid particles without metallic dissolution in the alkaline bath while at the same time providing a random microetched surface roughness to promote the subsequent coating and adherence of a substantially continuous thin conductive dry film of aluminum hydroxide containing graphite and powdered nickel, the reclaimed element having a substantially thin continuous conductive dry film of aluminum hydroxide containing graphite and powdered nickel.
