Method for preparing high-entropy borosilicate ceramic surface material by cold spraying
The invention discloses a method for preparing a high-entropy borosilicate ceramic surface material by cold spraying. The method comprises the following steps: 1, pretreatment of TiO2 ceramic powder: mixing TiO2 ceramic powder, ammonium sulfate powder and deionized water, carrying out hydrothermal treatment, cleaning to remove sulfate particle ions, and drying to obtain micron-sized TiO2 ceramic powder agglomerated by nano powder; and 2, preparing a TiO2 ceramic coating by cold spraying, namely preheating the TiO2 ceramic powder obtained in the step 1, and then cold spraying the TiO2 ceramic powder on the surface of a base material. The method has the beneficial effects that the micron-sized TiO2 powder agglomerated by nano powder is obtained by virtue of a hydrothermal treatment technology, and the TiO2 ceramic coating with the thickness of 20-400 microns can be prepared only by using low-cost compressed air as carrier gas. The method is high in deposition efficiency, the thickness of the TiO2 ceramic coating can be adjusted at will according to actual use conditions, and the method can be used for preparing the thick TiO2 ceramic coating.
本发明公开了一种利用冷喷涂制备高熵硼硅陶瓷表面材料的方法，包括以下步骤：第一步：TiO2陶瓷粉末的前处理将TiO2陶瓷粉末、硫酸铵粉末与去离子水混料进行水热处理，清洗去除硫酸根粒离子，干燥后得到由纳米粉团聚的微米级TiO2陶瓷粉末；第二步：冷喷涂制备TiO2陶瓷涂层将第一步得到的TiO2陶瓷粉末经预热后冷喷涂在基体材料表面。有益效果是：本发明借助水热处理技术得到由纳米粉团聚成的微米级TiO2粉体，仅仅使用低成本的压缩空气为载气就能制备厚度为20～400μm的TiO2陶瓷涂层。该方法沉积效率高，可根据实际使用情况随意调节TiO2陶瓷涂层的厚度，可以用来制备厚的TiO2陶瓷涂层。
