| Abstract | Liquid-phase-pressureless-sintered SiC-AlN-Y2O3 composites were coated by means of modified pack cementation process (OXPAC, OXidation-assisted-PAck Cementation) using rare-earth oxides, RE2O3 (RE=Sc, Er, Sm, Lu, Ho), as reactive powders. The coatings, composed by the oxidation products of SiC, AlN and rare-earth silicates, were adherent to the substrate, without porosity and with a thickness of 10μm. The oxidation resistance of the coated SiC-AlN-Y2O3 ceramics was also investigated at 1500°C for a period of 200h. The coated samples showed specific weight gain lower than the uncoated and pre-oxidised samples. Furthermore, the specific weight gain linearly increased with the rare-earth cationic radius. © 2010 Elsevier Ltd. |
