采用甘蔗渣浸渍环氧树脂后真空烧结制备生物形态木质陶瓷.研究了木质陶瓷的孔径分布及孔隙度,采用摩擦磨损试验机评价了木质陶瓷在干摩擦状态下的摩擦学性能,分析了木质陶瓷磨损后的表面形貌,简要讨论了木质陶瓷的磨损机理.研究表明:木质陶瓷的磨损机理主要以磨粒磨损和黏着磨损共同作用.木质陶瓷能够在磨损表面形成1层碳膜,具有良好的自润滑作用.甘蔗渣含量较高时,孔隙度较大,摩擦系数较大,磨损率较高,木质陶瓷的磨损主要表现为严重磨粒磨损,磨损表面无法形成碳膜.
After the epoxy resin was impregnated with bagasse, biomorphic wood ceramics were prepared by vacuum sintering.The pore size distribution and porosity of the wood ceramics were studied.The tribological properties of the wood ceramics under dry friction condition were evaluated by friction and wear testing machine.The wood ceramics The surface morphology after wear is briefly discussed.The wear mechanism of wood ceramics is briefly discussed.The research shows that the wear mechanism of wood ceramics is mainly abrasive wear and adhesive wear.The wood ceramics can form a carbon film on the wear surface with good When the content of bagasse is higher, the porosity is larger, the friction coefficient is larger and the wear rate is higher, the wear of wood ceramics is mainly the wear of abrasive grains, and the carbon film can not be formed on the worn surface.
