CERAMIC COMPOSITION FOR COATING SURGICAL AND DENTAL INSTRUMENTS

摘要

The working surfaces (3) of dental and surgical instruments (1) are coated with a ceramic material formed by plasma spraying of a composition including a cemented carbide matrix and a ceramic dispersion to form a hardened surface with improved gripping ability. The cemented carbide matrix preferably contains tungsten and/or chromium carbide and/or cobalt. The ceramic dispersion preferably consists of alumina or other oxides.
