High-performance carbon/carbon composite material bearing retainer with CVD (Chemical Vapor Deposition) coating and preparation method thereof
The invention discloses a high-performance carbon/carbon composite material bearing retainer with a CVD (chemical vapor deposition) coating and a preparation method of the high-performance carbon/carbon composite material bearing retainer, and relates to the technical field of preparation of bearing retainers. The preparation method comprises the following steps: firstly, puncturing a carbon fiber fabric preform by using high-strength carbon fibers, then preparing a high-density carbon/carbon composite material retainer blank by using a chemical vapor infiltration method, and carrying out graphitization heat treatment and finish machining to obtain the carbon/carbon composite material retainer. And then, depositing an isotropic (ISO) pyrolytic graphite coating on the surface by using a CVD (Chemical Vapor Deposition) technology to obtain a final finished product. The retainer treated by the method has the characteristics of more excellent wear resistance and friction reduction, the rotating speed and the use temperature of the bearing can be improved, and the service life of the bearing is further prolonged.
本发明公开了一种具有CVD涂层的高性能炭/炭复合材料轴承保持架及其制备方法，涉及轴承保持架制备技术领域。本发明首先利用高强度碳纤维穿刺碳纤维织物预制体，然后利用化学气相渗透方法制备高密度的炭/炭复合材料保持架坯体，经石墨化热处理和精加工后，得到炭/炭复合材料保持架。随后利用CVD技术在其表面沉积各向同性（ISO）热解石墨涂层，得到最终成品。经该方法处理后的保持架具有更优异的耐磨减摩特点，可提高轴承的转速和使用温度，进一步提升轴承使用寿命。
