Infiltration agent with multi-layer coating structure and preparation method of infiltration agent
The invention belongs to the technical field of infiltration agents, and provides a preparation method of an infiltration agent with a multi-layer coating structure. The ceramic powder and the carbon powder are used as raw materials, the mixed powder is prepared through ball milling and mixing, the carbon powder is used as a nucleation point for preparing a carbon layer through vapor deposition, and the deposition uniformity and efficiency can be improved; propylene, hydrogen and argon are used as deposition atmospheres for vapor deposition, and a carbon layer is deposited on the surface of the ceramic layer, so that the surface tension of the infiltration agent is reduced, the wettability of the infiltration agent is improved, the infiltration agent with a multi-layer coating structure is prepared, the wettability of a melt material in a high-temperature state can be effectively improved, and the performance of the infiltration agent is improved. The filling property of the melt to the interior of the prefabricated body is improved, and the porosity of the material is reduced. The result of the embodiment shows that the infiltration agent with the multilayer coating structure prepared by the preparation method provided by the invention has a double-layer structure and is good in filling property.
本发明属于熔渗剂技术领域，提供了一种多层包覆结构的熔渗剂的制备方法。本发明以陶瓷粉末和碳粉为原料，先通过球磨混合制得混合粉末，碳粉作为气相沉积制备碳层的形核点，有利于提高沉积的均匀性和效率；再以丙烯、氢气和氩气作为沉积气氛进行气相沉积，在陶瓷层表面沉积碳层，从而降低了熔渗剂的表面张力，提高了熔渗剂的润湿性，进而制得了具有多层包覆结构的熔渗剂，可以有效改善高温状态下熔体材料的润湿性能，提高熔体对预制体内部的填充性，降低材料的孔隙率。实施例的结果显示，本发明提供的制备方法制备的多层包覆结构的熔渗剂具有双层结构，并且填充性好。
