Ultrahigh-temperature ceramic coating on surface of ceramic-based composite material and preparation method of ultrahigh-temperature ceramic coating
The invention discloses a superhigh-temperature ceramic coating on the surface of a ceramic-based composite material and a preparation method of the superhigh-temperature ceramic coating. The preparation method comprises the following steps: (1) preparing a resin carbon coating solution by taking resorcinol, a formaldehyde aqueous solution, NaHCO3 and PVA as raw materials, or preparing the resin carbon coating solution by taking phenolic resin, hexamethylenetetramine, alcohol, acetone and thermoplastic resin as raw materials; (2) pulling and dipping the ceramic-based composite material in a resin carbon solution, and then sequentially carrying out segmented temperature control curing and pretreatment; and (3) pulling and dipping in a metal oxide solution, and then sequentially carrying out segmented temperature control curing and pyrolysis treatment, thereby obtaining the product. The production and manufacturing cost of the coating is reduced, the problems that the coating is complex in preparation operation, uneven, incapable of resisting high temperature and the like are solved, and the prepared coating has the properties of oxidation resistance, high temperature resistance and corrosion resistance, and is compact and uniform in structure, free of protrusions on the surface and low in roughness.
本发明公开了一种陶瓷基复合材料表面超高温陶瓷涂层及其制备方法，其制备方法包括以下步骤：(1)以间苯二酚、甲醛水溶液、NaHCO3和PVA为原料制备树脂碳涂层溶液，或以酚醛树脂、六次甲基四胺、酒精、丙酮和热塑性树脂为原料制备树脂碳涂层溶液；(2)将陶瓷基复合材料于树脂碳溶液中提拉浸渍，然后依次分段控温固化、预处理；(3)再于金属氧化物溶液中提拉浸渍，然后依次分段控温固化，热解处理，制得。本发明降低了涂层生产制造的成本，解决了涂层制备操作复杂、不均匀以及无法耐高温等问题，制得的涂层具备抗氧化、耐高温、耐腐蚀的性能，结构致密均匀，表面无凸起，粗糙度低。
