ZHAO MINGXIAN

The invention relates to the technical field of anti-oxidation graphite material coating processing methods, in particular to a method for comprehensively coating SiC on the surface layer of anti-oxidation graphite. The method comprises the following steps of powder weighing, feeding, capping reaction, blast circulation, coating, waste gas circulation, coating lifting and reset output. According to the method, elemental silicon powder and silicon dioxide powder in the capping reaction step react to form silicon oxide gas, in the blast circulation step, a blast mechanism conveys the silicon oxide gas to a coating platform to coat a graphite workpiece on the platform to form a silicon carbide coating, and in the whole reaction process, gas in a reaction kettle forms circular flow, the silicon oxide gas can always react around the graphite workpiece, so that the technical problem of non-uniform coating of the existing graphite workpiece is solved.

本发明涉及抗氧化石墨材料涂层加工方法技术领域，具体为一种抗氧化石墨表层SiC全面涂层方法，包括以下步骤：粉料称取→加料→封盖反应→鼓风循环→涂层→废气循环→抬升涂层→复位输出，通过封盖反应步骤中的单质硅粉末与二氧化硅粉末通过反应形成氧化硅气体，并利用鼓风循环步骤中，鼓风机构将氧化硅气体输送至涂层平台对平台上的石墨工件进行涂层，形成碳化硅涂层，整个反应过程中，反应釜内气体形成循环流动，氧化硅气体能始终围绕石墨工件进行反应，解决了现有石墨工件涂层不均匀的技术问题。
