Preparation method for silicon carbide fiber with porous alumina coating
The invention relates to a preparation method for a silicon carbide fiber with porous alumina coating, which includes the following steps: an appropriate amount of aluminium isopropoxide and lactic acid solution is added into isopropanol or deionized water as solvent, so that mixed solution is obtained, and after water bath heating and heating reflux reaction, alumina sol is obtained; a silicon carbide fiber is immersed in the alumina sol, and is then dried under vacuum, the process is repeated until needed coating thickness is obtained, the silicon carbide fiber is then put into an oven, and is kept under high temperature for a period of time, and after the silicon carbide fiber is cooled to room temperature, the silicon carbide fiber with the alumina coating is obtained. The process of the treatment method provided by the invention is simple, expensive and complex equipment is not needed, and the manufacturing cost is low; moreover, the prepared coating has a porous structure, is uniform in composition, and is tightly bonded with the silicon carbide fiber.
