Carbon-ceramic brake disc with wear-resistant coating and preparation method of carbon-ceramic brake disc
The invention relates to the field of carbon-ceramic materials, and particularly discloses a carbon-ceramic brake disc with a wear-resistant coating and a preparation method thereof.The preparation method comprises the following steps that a carbon-carbon brake disc blank is sprayed with a binding agent to form a binding layer, then a wear-resistant agent is flatly laid, and the wear-resistant coating is obtained; wherein the binder is prepared from the following raw materials: phenolic resin, silicon dioxide powder and carbon powder; the wear-resistant agent is prepared from the following raw materials: phenolic resin, carbon powder and silicon carbide powder; the carbon-carbon brake disc blank treated in the step S1 is pressed, cured and formed; carrying out carbonization treatment; densification treatment: carrying out molten silicon infiltration; and sequentially carrying out finish machining and heat treatment on the carbon-carbon brake disc coating blank subjected to siliconing densification treatment to obtain the carbon-ceramic brake disc. The invention further discloses the carbon-ceramic brake disc manufactured through the method. The carbon-ceramic brake disc has the advantage that the problem that in the ceramic process of an existing carbon-carbon brake disc, due to the fact that the difference between the thermal expansion coefficients of a coating and a blank body is large, cracking is caused is solved.
本申请涉及碳陶材料领域，具体公开了一种具有耐磨涂层的碳陶刹车盘及其制备方法，其制备方法包括以下步骤：碳碳刹车盘胚体上喷涂有粘结剂形成粘结层，再平铺耐磨剂，得到耐磨涂层；其中，粘结剂由以下原料制得：酚醛树脂、二氧化硅粉末、碳粉；耐磨剂由以下原料制得：酚醛树脂、碳粉和碳化硅粉末；对步骤S1中处理后的碳碳刹车盘胚体压制固化成型；碳化处理；致密化处理：进行熔硅浸渗；对渗硅致密化处理后的碳碳刹车盘涂层胚体依次进行精加工和热处理，制得碳陶刹车盘。本申请还公开了采用上述方法制得的碳陶刹车盘，本申请具有解决现有碳碳刹车盘陶瓷化过程中由于涂层与胚体热膨胀系数相差大导致开裂问题的特点。
