The invention belongs to the technical field of carbon-ceramic brake discs, and particularly relates to a carbon-ceramic brake disc coating repairing agent and a carbon-ceramic brake disc coating repairing method. The carbon ceramic brake disc coating repairing agent provided by the invention comprises 70-85% of silicon carbide, 5-20% of resin, 5-10% of carbon powder and 5-10% of silicon powder. The carbon-ceramic brake disc coating repairing agent provided by the invention is suitable for repairing carbon-ceramic brake discs of which the coatings are damaged during installation and carbon-ceramic brake discs of which the coatings are cracked by unknown objects and fall off during use. The invention provides a method for repairing a coating of a carbon-ceramic brake disc, which comprises the following steps of: coating a damaged coating area of the carbon-ceramic brake disc with a damaged coating with a repairing agent, and then sequentially pressing, siliconizing and polishing. The carbon-ceramic brake disc coating repairing agent provided by the invention can effectively repair a carbon-ceramic brake disc coating, is convenient and easy to implement, and can effectively prevent oxygen from entering the carbon-ceramic brake disc coating after repairing and prevent carbon fibers from being oxidized.

本发明属于碳陶刹车盘技术领域，具体涉及一种碳陶刹车盘涂层修补剂以及一种碳陶刹车盘涂层修补方法。本发明提供的碳陶刹车盘涂层修补剂，包括：碳化硅70～85％、树脂5～20％、碳粉5～10％、硅粉5～10％。本发明提供的碳陶刹车盘涂层修补剂适用于修补在安装时涂层受到破损的碳陶刹车盘和一些使用过程被不明物体撞裂脱落涂层的碳陶刹车盘。本发明提供了一种碳陶刹车盘涂层修补方法，将修补剂涂布在涂层破损的碳陶刹车盘的涂层破损区域，然后依次进行压制、渗硅和打磨。本发明提供的碳陶刹车盘涂层修补剂能够有效对碳陶刹车盘涂层进行修补，不仅方便易行，且修补后能有效的阻挡氧气的进入，防止碳纤维的氧化。
