Beschreibung
Zusammenfassung:	A composite assembly of a relatively inexpensive ceramic, such as alumina, with a skin, or covering, of a high wear ceramic, such as sapphire, adapted to be used in semiconductor processing environments subjected to high levels of corrosion and/or erosion. The design life of the composite assembly may be significantly longer than previously used components. The composite assembly may have its ceramic pieces joined together with aluminum, such that the joint is not vulnerable to corrosive aspects to which the composite assembly may be exposed.
