Silicon carbide nanowire composite anti-oxidation coating of carbon material product and application of silicon carbide nanowire composite anti-oxidation coating
The invention relates to the technical field of medium and low temperature oxidation resistance of carbon materials. The invention particularly relates to a silicon carbide nanowire composite anti-oxidation coating of a carbon material product and application of the silicon carbide nanowire composite anti-oxidation coating. The coating is prepared from the following raw materials in percentage by mass: 10%-20% of graphite powder, 55%-70% of silicon powder, 9%-15% of a catalyst and 5%-28% of yttrium oxide, the catalyst is preferably ferric nitrate. The application comprises the following steps: polishing and cleaning a C/C composite sample; then preparing an impregnation liquid; soaking the treated sample in a soaking solution; then drying treatment is conducted at the temperature below 150 DEG C to obtain a dried sample, the dried sample is fed into a heating furnace, heating treatment is conducted under the protective atmosphere or the vacuum condition to obtain a product, and the temperature is controlled to be 1200-1400 DEG C during heating treatment. The component design is reasonable, the application process is simple and controllable, the coating performance is excellent, and industrial application is facilitated.
本发明涉及碳材料中低温抗氧化技术领域；具体涉及一种碳材料制品的碳化硅纳米线复合抗氧化涂层及其应用。所述涂料所用原料以质量百分比计，由下述组分组成：石墨粉10％～20％，硅粉55％～70％，催化剂9％～15％，氧化钇5％～28％；所述催化剂优选为硝酸铁。所述应用包括：将C/C复合样品进行抛光清洗；然后制备浸渍液；接着将处理后的样品置于浸渍液中浸渍；接着先在150℃以下进行干燥处理，得到干燥样品，干燥样品送入发热炉内，在保护气氛下或真空条件下进行加热处理，得到产品，加热处理是控制温度为1200～1400℃。本发明组分设计合理，应用工艺简单可控，涂层性能优良，便于产业化应用。
