COATED CERAMIC PARTS AND A METHOD FOR MANUFACTURE THEREOF

摘要

FIELD: ceramics. ^ SUBSTANCE: invention relates to coated ceramic parts designed for use in operations involving dipping or partial dipping into molten glass, in particular in manufacture of glass articles. Ceramic element with coating on its surfaces contacting with molten glass contains basic coating 0.05 mm thick made up of chromium/aluminum/cobalt/yttrium composite powder and coating 0.15 mm thick made up of preliminarily molten cerium/yttrium-stabilized zirconium oxide laid above basic coating. Coatings are applied in the form of powder using fire sputtering technique. ^ EFFECT: prolonged service time of ceramic parts. ^ 11 cl, 3 dwg
