Beschreibung
Zusammenfassung:	An abrasion resistant article (10, 30, 40) for use, while submerged or partly submerged in molten glass, in a glass article manufacturing operation, the article having a ceramic element (12, 32, 42) coated on its molten glass contacting surfaces with a thin base coating of a nickel chromium-aluminum-cobalt-yttria-composite powder (18, 34, 44) and a somewhat thicker coating'(20, 36, 46) of a prealloyed ceria-yttria stabilized zirconium oxide superimposed an the base coating.
