ZrB2-SiC-Mo (Six, Al<1-x>) 2 zero-ablation coating and hot-pressing preparation method thereof
The invention discloses a ZrB2-SiC-Mo (Six, Al<1-x>) 2 zero-ablation coating and a hot-pressing preparation method thereof. The preparation method comprises the following steps of: weighing powder raw materials according to predetermined mass percentages; carrying out ball milling on the powder raw materials by adopting a ball mill, and uniformly mixing the powder raw materials to form a powder material; adding a binder and deionized water into the powder material, and uniformly stirring to form a mixture; coating the surface of a component with the mixture; putting the component into a mold, and filling the periphery of the component with filling powder; carrying out hot pressing by adopting a hot press under a protective atmosphere; adding a pressure maintaining process for pressure maintaining while enabling the mold and the sintered body to be freely cooled; and releasing the pressure to form the carbon/ carbon composite material zero-ablation coating. The method has the advantages that the process conditions are easy to control, the cost is low, and the problem that the surface oxidation resistance of an existing carbon/carbon composite material is poor in an aerobic environment can be solved.
本发明公开了一种ZrB2‑SiC‑Mo(Six,Al1‑x)2零烧蚀涂层及其热压制备方法，该制备方法包括以下步骤：按照预定质量百分比称取粉末原料；采用球磨机对粉末原料进行球磨，使粉末原料混合均匀，形成粉末材料；向粉末材料中添加粘结剂和去离子水，搅拌均匀，形成混合物；将混合物涂覆在构件表面；将构件放入模具中，并在构件周围充满填充粉；在保护气氛下采用热压机进行热压；使模具和烧结体自由冷却的同时附加保压工艺保压；泄压，形成炭/炭复合材料零烧蚀涂层。采用上述方法具有工艺条件容易控制、成本低的优点，能够解决现有炭/炭复合材料在有氧环境下表面抗氧化性较差的问题。
