Nano ceramic composite spraying powder and preparation method thereof
The invention discloses nano ceramic composite spraying powder and a preparation method thereof, and particularly relates to the technical field of nano high-temperature-resistant ceramic powder coating materials, the nano ceramic composite spraying powder comprises ZrOCl2. 8H2O (zirconium oxychloride), Y (NO3) 3.6 H2O (yttrium nitrate), Sc2O3 (scandium oxide), a dispersing agent, a solvent and a precipitator, the dispersing agent is polyethylene glycol (PEG), the solvent is absolute ethyl alcohol/water, and the precipitator is ammonia water. The melting point of a nano ceramic phase in the nano ceramic composite powder is low, the nano ceramic phase can be easily and fully heated in the spraying process, a high-quality spraying layer can be prepared, and when ethanol water serves as a solvent, powder prepared in a reverse dripping and depositing mode is agglomerated loosely; the powder prepared by forward drop deposition forms a hard aggregate, so that two kinds of powder with different particle sizes can be obtained, and the powder can be conveniently prepared according to requirements; the particle size of the powder prepared by adopting a reverse drop deposition mode is about 20nm, and the powder is relatively loose in agglomeration; the particle size of the powder prepared by forward drop deposition is about 30nm, and the powder forms a hard aggregate.
本发明公开了一种纳米陶瓷复合喷涂粉末及其制备方法，具体涉及纳米耐高温陶瓷粉涂层材料技术领域，包括ZrOCl2·8H2O(氯氧化锆)、Y(NO3)3·6H2O(硝酸钇)、Sc2O3(氧化钪)、分散剂、溶剂和沉淀剂，所述分散剂为聚乙二醇(PEG)，所述溶剂为无水乙醇/水，所述沉淀剂为氨水。纳米陶瓷复合粉体中纳米陶瓷相的熔点较低，并易于在喷涂过程中得到充分加热，能够制得优质的喷涂层，乙醇水为溶剂时，采用反向滴淀方式制备的粉末团聚较松散；采用正向滴淀制备的粉末形成硬团聚体，从而可以得到粒径不同的两种粉末，便于根据需求制备；采用反向滴淀方式制备的粉末的粒径约为20nm，粉末团聚较松散；采用正向滴淀制备的粉末粒径约为30nm，粉末形成硬团聚体。
