Composite tantalum carbide coating on surface of graphite device and coating method of composite tantalum carbide coating
The invention relates to the technical field of carbon material coatings, and discloses a composite tantalum carbide coating on the surface of a graphite device and a coating method thereof.The composite tantalum carbide coating comprises a carbon layer, a middle tantalum carbide layer and a tantalum carbide outer layer which are sequentially arranged in a covering mode from the surface of the graphite device to the outside; the middle tantalum carbide layer is obtained by reacting tantalum oxide, tantalum carbide and PVA glue in any proportion; the tantalum carbide outer layer is prepared from the following components in percentage by mass: 2 to 8 percent of tantalum chloride, 0.3 to 0.8 percent of chromium carbide, 2 to 10 percent of PVA glue and 15 to 25 percent of ethylene glycol through reaction. According to the composite tantalum carbide coating on the surface of the graphite device, the composite tantalum carbide coating on the surface of the graphite device, which has stronger binding force and higher surface smoothness, can be formed through the mutual combination effect of multiple layers of composite coatings, and the relative requirements of preparation process conditions of the composite tantalum carbide coating on the surface of the graphite device are lower.
本发明涉及碳材涂层技术领域，公开了一种石墨器件表面复合碳化钽涂层及其涂覆方法，沿石墨器件表面向外，所述复合碳化钽涂层包括依次覆设的碳层、中间碳化钽层和碳化钽外层；所述中间碳化钽层由氧化钽、碳化钽和PVA胶以任意比例反应得到；按质量分数计，所述碳化钽外层由2‑8％氯化钽、0.3‑0.8％碳化铬、2‑10％PVA胶和15‑25％乙二醇反应得到。本发明中的石墨器件表面复合碳化钽涂层，通过设置的多层复合涂层之间的相互结合作用，可形成具有更强结合力和更高表面光洁度的石墨器件表面复合碳化钽涂层，且其制备工艺条件相对要求更低。
