Composite coating and preparation method thereof, carbon/carbon crucible and application
The invention relates to a composite coating, a preparation method of the composite coating, a carbon/carbon crucible and application of the carbon/carbon crucible. The composite coating is combined on the surface of the carbon/carbon substrate; the composite coating comprises a resin roasting substance, a graphite carbon substance, a first carbon substance and a second carbon substance, at least one part of the resin roasting substance and the first carbon substance form a framework with a communicating pore channel, and at least one part of the graphite carbon substance and the second carbon substance are filled in the communicating pore channel. The composite coating is tightly combined with a carbon/carbon substrate, and is relatively good in corrosion resistance and relatively long in service life. According to the provided preparation method, the framework coating is formed on the carbon/carbon substrate firstly, then the pore channels of the framework coating are filled with the carbonaceous particles through the vapor deposition method, the process is simple, processing is easy, the production efficiency is high, the yield is high, the prepared composite coating is tightly combined with the carbon/carbon substrate, the chemical stability of the coating is high, and the service life of the coating is prolonged. And the service life of the thermal field structural member can be effectively prolonged.
本发明涉及一种复合涂层及其制备方法、碳/碳坩埚及应用。该复合涂层结合于碳/碳基底之表面；复合涂层包括树脂焙烧物和石墨类碳物质，第一碳物质和第二碳物质，其中，至少一部分树脂焙烧物第一碳物质形成具有连通孔道的骨架，石墨类碳物质第二碳物质的至少一部分填充于连通孔道内。该复合涂层与碳/碳基底结合紧密，可以较好地耐腐蚀，使用寿命较长。提供的制备方法先在碳/碳基底上形成骨架涂层，再采用气相沉积法在骨架涂层的孔道内填充碳质颗粒，工艺简单、易于加工、生产效率高且成品率高，而且制备得到的复合涂层与碳/碳基底结合紧密、涂层的化学稳定性高，可以有效延长热场结构件的使用寿命。
