ABSTRACT:
An improved ware plate useful for materials feeder equipment, and the like, includes highly efficient, durable and wear and abrasion resistant sliding surface for slidably contacting elements of the feeder equipment. In particular, the ware plate has a tetragonal zirconia polycrystal ceramic sliding surface for contacting an element of the feeder equipment having a zirconia-alumina ceramic composite sliding surface. Alternatively, the sliding surface of the ware plate is zirconia-alumina ceramic composite for sliding contact with the element of the feeder equipment having a tetragonal zirconia polycrystal ceramic sliding surface.
