中文摘要： 稻壳焚烧与储存给环境带来了严重的危害，合理利用稻壳资源是迫切需要解决的问题。稻壳基陶瓷材料的开发是稻壳资源化利用的新途径之一，但稻壳基陶瓷的易吸湿性严重限制了其应用范围。本项目拟通过化学镀法实现稻壳基陶瓷颗粒的表面金属化改性，抑制其吸湿性并增强其导热性，探索表面金属化稻壳基陶瓷颗粒金属镀层的摩擦剥离、转移及对摩擦副的修复行为；再选择合适的摩擦催化剂，研究金属镀层剥离后的稻壳基陶瓷颗粒在催化剂表面的晶型转变行为，探索无定形碳向润滑结构的石墨碳转变的条件及相关机制。本项目从稻壳基陶瓷颗粒表面金属化抑制吸湿性、摩擦剥离金属镀层对摩擦副表面的修复、摩擦催化诱导形成润滑结构的石墨碳这三个方面出发，改善稻壳基陶瓷颗粒的摩擦学性能，在碳材料摩擦磨损机理、摩擦催化机理与稻壳的综合利用等领域具有较好的理论与实际意义。

英文摘要： The incineration and storage of rice husk has brought the serious environmental harm and the utilization of rice husk has become a pressing problem to be solved. One of the approaches to utilize the rice husk is the preparation of rice husk ceramic (RHC) particles. But the hygroscopic surface of RHC limits its applications. In order to weaken its hygroscopic property and strengthen the thermal conductivity, the chemical plating method will be used to metalize the RHC surface to prevent H2O from entering RHC particles in the research project. The behaviors of exfoliation, transferring, and repairing friction pair of the metallization RHC particles will be studied during the friction period. At the same time, the possible RHC crystal transformation on the surface of the preferred catalysts will be investigated. The transforming conditions and mechanism from amorphous carbon into graphite-microcrystal will also be researched by a series of systematic tribological tests. To improve the tribological properties of RHC particles, the project will research the surface metallization for weakening the hygroscopic property, the exfoliation and transferring of the metal plating layer for repairing the friction pair, and the crystal transformation from amorphous carbon into graphite-microcrystal on the surface of catalysts. The results will have excellent theoretical or practical significances in areas, such as the carbon materials tribology, the tribological catalysis, and the utilization of rice husk.
