Plasma-sprayed ceramic coatings for SiAlON ceramics
UNSPECIFIED (1996) Plasma-sprayed ceramic coatings for SiAlON ceramics. JOURNAL OF THE EUROPEAN CERAMIC SOCIETY, 16 (10). pp. 1133-1139. ISSN 0955-2219Full text not available from this repository.
Plasma-sprayed coatings of yttria-stabilized ZrO2 and Al2O3.TiO2 used as a protective barrier on beta-Si3N4-based sialon ceramics were investigated. The coatings showed better cohesion with the pre-oxidized surfaces due to the reaction between the SiO2-rich oxidation layer and the coating materials. Formation of low thermal expansion zircon and aluminium titanate on the pre-oxidized ceramic was studied using scanning electron microscopy and X-ray diffraction. Preliminary experiments on oxidation and molten metal immersion, showed that the coatings provide significant protection against oxidation and molten metal attack. (C) 1996 Elsevier Science Limited.
