Preparation method of high-bonding-strength carbon-ceramic brake coating disc
The invention discloses a preparation method of a carbon-ceramic brake coating disc with high bonding strength. The preparation method comprises the following steps that the upper surface and the lower surface of a carbon/carbon composite material disc body are scraped to be flat, then grooving and galling treatment are conducted, non-resin powder materials in a coating are subjected to surface activating treatment and air drying, then the non-resin powder materials are mixed with resin, a coating mixture is flatly laid in a mold, the grooved and galled carbon/carbon composite material disc body is placed in the mold, and the carbon/carbon composite material disc body is manufactured. And a part of the same coating mixture is placed on the tray body and is flatly paved. And then carrying out hot pressing, carbonization and ceramization to obtain the carbon-ceramic brake coating disc. The process is simple, large-scale production is easy to realize, the bonding strength between the coating and the disc body is high, the thickness and flatness of the coating are easy to control, and the problems that the coating is easy to fall off and crack, the production process is complex and low in efficiency, and the thickness of the coating is difficult to control can be effectively solved.
本发明公开了一种高粘结强度碳陶制动涂层盘的制备方法。所述制备方法包括如下步骤：将碳/碳复合材料盘体上下表面刮平，然后进行开槽且拉毛处理，将涂层中非树脂粉体材料进行表面活化处理并晾干，然后与树脂混合，将一份涂层混合物平铺进模具中，放入开槽和拉毛的碳/碳复合材料盘体，再放一份一样的涂层混合物在盘体上方并铺平。然后进行热压、碳化和陶瓷化，获得碳陶制动涂层盘。本发明工艺简单，易实现规模化生产，涂层与盘体之间结合强度高，涂层厚度及平整度容易控制，可以有效解决涂层易脱落开裂、生产过程复杂效率低，且涂层厚度难控制的问题。
