Roll having zirconia coating

摘要

Rolls (154) include a core (1541) and a stabilized zirconia-containing outer coating (1542) on the core. The outer coating can also include titania. The outer coatings have smooth finishes and controlled electrical properties. The outer coatings of the rolls can be finished to a highly smooth finish in reduced cycle times. The rolls can be used in electrostatographic imaging apparatus as charge donor rolls.
