The invention discloses a ceramic component gradient modified C/C composite material component as well as a preparation method and application thereof, and relates to the technical field of carbon materials. The method comprises the following steps: processing a C/C composite material into a component with a specific shape; pressing the ceramic infiltration powder into a ceramic chip; the preparation method comprises the following steps: placing a ceramic wafer at a specified position of a component, placing the ceramic wafer and the component in a selectively perforated graphite mold, vacuumizing to 0.1-500Pa, and then keeping the temperature at 1200-2100 DEG C for 0.5-10h in an inert atmosphere to obtain the ceramic component gradient modified C/C composite material component. According to the method, one-step efficient preparation of the ceramic component gradient modified C/C composite material component is realized by optimizing a reactive melt infiltration (RMI) process.

    本发明公开了一种陶瓷组元梯度改性C/C复合材料构件及其制备方法和应用,涉及碳材料技术领域。所述方法包括将C/C复合材料加工成特定形状的构件;将陶瓷熔渗粉料压制成陶瓷片;将陶瓷片置于构件的指定位置,将二者置于选择性开孔的石墨模具内,抽真空至0.1~500Pa,随后在惰性气氛中,于1200~2100℃,保温0.5~10h,获得陶瓷组元梯度改性C/C复合材料构件。本发明通过优化反应熔渗(RMI)工艺,实现陶瓷组元梯度改性C/C复合材料构件的一步高效制备。
