Preparation method of aerogel surface anti-scouring protective coating
The invention belongs to the technical field of thermal spraying, and particularly relates to a preparation method of an aerogel surface anti-scouring protective coating. The method comprises the following steps: selecting an aerogel material as a sprayed body; selecting a coating material according to a use environment and a temperature-resistant range of the aerogel material; a thermal spraying process is adopted, the anti-scouring protective coating is prepared on the surface of the aerogel material through spraying deposition by setting spraying process parameters, and the spraying process parameters include that the spraying power is set between 25 KW and 50 KW, the spraying speed is set between 500 mm/s and 3000 mm/s, and the spraying distance is controlled between 10 mm and 80 mm. The deposition of the protective coating which is high in quality, uniform in distribution, high in cohesion strength and excellent in anti-scouring performance is realized by accurately controlling thermal spraying process parameters.
本发明属于热喷涂技术领域，具体是涉及一种气凝胶表面抗冲刷防护涂层的制备方法。该方法包括：选择气凝胶材料作为被喷涂体；根据使用环境和所述气凝胶材料的耐温范围选择涂层材料；采用热喷涂工艺，通过设置喷涂工艺参数在所述气凝胶材料表面喷涂沉积制备抗冲刷防护涂层，所述喷涂工艺参数包括：喷涂功率设定在25KW至50KW之间，喷涂速度设定在500mm/s至3000mm/s之间，喷涂距离控制在10mm至80mm之间。本发明通过精确控制热喷涂工艺参数实现了高质量、均匀分布且具有高内聚强度和优异抗冲刷性能的防护涂层的沉积。
