Processing technology of glassy carbon coating of graphite component
The invention relates to the technical field of glassy carbon coating processing, in particular to a processing technology of a glassy carbon coating of a graphite component, which comprises the following steps: S1, selecting a graphite material with specific porosity as a base material; s2, carrying out surface cleaning and preheating treatment on the graphite base material; s3, preparing a phenolic resin solution according to a specific proportion, and controlling the viscosity and the concentration of the solution; s4, immersing the graphite base material into a phenolic resin solution, and carrying out immersion treatment; s5, performing low-temperature curing on the impregnated graphite material; s6, heating the low-temperature cured graphite material to 1000 DEG C in a vacuum environment, and carrying out carbonization treatment; and S7, the carbonized material is subjected to high-temperature graphitization treatment, and a compact glassy carbon coating is formed. According to the invention, the phenolic resin is used to form the glassy carbon coating in the graphite material, so that the corrosion resistance and the stability of the material are remarkably improved, the production cost and the environmental influence are reduced, and the operability and the applicability are improved.
本发明涉及玻璃碳涂层加工技术领域，具体涉及一种石墨构件的玻璃碳涂层的加工工艺，包括以下步骤：S1：选用具有特定孔隙率的石墨材料作为基材；S2：对石墨基材进行表面清洁和预热处理；S3：按特定比例配制酚醛树脂溶液，控制溶液的粘度和浓度；S4：将石墨基材浸入酚醛树脂溶液中，进行浸渍处理；S5：将浸渍后的石墨材料进行低温固化；S6：将低温固化后的石墨材料在真空环境下升温至1000℃，进行碳化处理；S7：碳化处理后的材料，进行高温石墨化处理，形成致密的玻璃碳涂层。本发明，通过使用酚醛树脂在石墨材料中形成玻璃碳涂层，显著提升了材料的耐腐蚀性和稳定性，同时降低了生产成本和环境影响，提高了操作性和适用性。
