ZrSiO4/SiC Oxidation Protective Coating for Carbon/Carbon Composites Prepared by Hydrothermal Electrophoretic Deposition
In order to improve the oxidation resistance of carbon/carbon (C/C) composites,a ZrSiO4 coating on SiC pre-coated C/C composites was prepared by a hydrothermal electrophoretic deposition process.The phase composition,surface and cross-section microstructure,oxidation protective property of the as-prepared ZrSiO4/SiC coating were investigated.Results show that hydrothermal electrophoretic deposition is an effective route to achieve crack-free ZrSiO4 outer coating.The ZrSiO4/SiC coating can protect C/C composites from oxidation at 1773 K for 332 h with a mass loss rate of only 4.83 × 10-5g/cm2·h.
