Method for preparing Glass-MoSi2atY2O3-SiC anti-oxidation coating on surface of carbon/carbon composite material
The invention discloses a method for preparing a Glass-MoSi2-coated Y2O3-SiC anti-oxidation coating on the surface of a carbon/carbon composite material. The method comprises the following steps: step 1, preparing MoSi2-coated Y2O3 microcapsules; 2, preparing a carbon/carbon composite material with a SiC inner coating on the surface; step 3, preparing an outer coating of a MoSi2atY2O3 core-shell structure by using self-made hydrothermal electric deposition equipment; step 4, preparing glass powder; and step five, mixing the glass powder prepared in the step four with molybdenum disilicide according to a mass ratio of (4-8): 1, diluting with absolute ethyl alcohol to form slightly flowing slurry, brushing on the surface of the sample by using a brush, and preserving heat for 2-6 minutes at the temperature of 1400 DEG C in an argon atmosphere to finally obtain a compact high-temperature oxidation-resistant coating. According to the method disclosed by the invention, the compact Glass-MoSi2-coated Y2O3-SiC anti-oxidation coating is formed on the surface of the carbon/carbon composite material.
本发明公开了一种碳/碳复合材料表面制备Glass‑MoSi2@Y2O3‑SiC抗氧化涂层的方法，包括以下步骤：步骤一、制备MoSi2@Y2O3微胶囊；步骤二、制备表面含有SiC内涂层的碳/碳复合材料；步骤三、使用自制水热电沉积设备制备MoSi2@Y2O3核壳结构的外涂层；步骤四、配置玻璃粉体；步骤五、将步骤四制备的玻璃粉体与二硅化钼按质量比为(4～8):1进行混合，再用无水乙醇稀释成轻微流动的浆料，再用刷子刷涂在上述试样表面，然后在氩气气氛下1400℃保温2～6min，最终得到致密的高温抗氧化涂层；本发明的方法在碳/碳复合材料表面形成致密的Glass‑MoSi2@Y2O3‑SiC抗氧化涂层。
