Ceramic slurry, coating for improving corrosion resistance of carbon-carbon composite material and preparation method of coating
The invention relates to the technical field of corrosion resistance of carbon-carbon materials, and particularly discloses ceramic slurry, a coating for improving corrosion resistance of a carbon-carbon composite material and a preparation method of the coating. The ceramic slurry comprises the following raw materials in parts by weight: 45-60 parts of kaolin powder, 35-50 parts of bentonite powder, 8-15 parts of silicon carbide powder, 10-30 parts of hafnium carbide composite powder, 260-400 parts of a solvent and 0.4-0.6 part of a sintering aid; the hafnium carbide composite powder is prepared by sintering raw materials including hafnium carbide powder, zirconium powder and silicon carbide whiskers; the raw materials of the ceramic slurry are mixed to obtain the ceramic slurry; and impregnating the ceramic slurry on the surface of the carbon-carbon composite material, removing a solvent, and sintering to form the ceramic coating on the surface of the carbon-carbon composite material. The ceramic coating is compact in structure and has good fracture toughness and silicon steam corrosion resistance.
本申请涉及碳碳材料防腐的技术领域，具体公开了一种陶瓷浆料、改善碳碳复合材料抗腐蚀性的涂层及其制备方法。陶瓷浆料包括以下重量份的原料：高岭土粉末45‑60份，膨润土粉末35‑50份，碳化硅粉末8‑15份，碳化铪复合粉末10‑30份，溶剂260‑400份，烧结助剂0.4‑0.6份；所述碳化铪复合粉末是将包括碳化铪粉末、锆粉以及碳化硅晶须的原料烧结后制备得到；陶瓷浆料的各原料混合即得到陶瓷浆料；将陶瓷浆料浸渍在碳碳复合材料表面后经溶剂脱除、烧结，在碳碳复合材料表面形成陶瓷涂层。该陶瓷涂层结构致密，具有较好的断裂韧性和耐硅蒸汽腐蚀能力。
