Carbon-based composite material bone screw and preparation method thereof
The invention discloses a carbon-based composite material bone screw and a preparation method thereof, the bone screw comprises a screw cap and a screw rod, the matrix of the bone screw is composed ofa carbon/carbon/silicon carbide composite material, and the surface of the matrix is coated with a DLC coating. The bone screw is prepared from a carbon fiber fabric as a raw material through the process steps of densifying matrix carbon, machining, densifying matrix silicon carbide, carrying out high-temperature treatment, depositing a DLC coating and the like. The bone screw has the advantagesof being light, good in biocompatibility, excellent in mechanical property, simple in preparation process, high in operability and beneficial to industrial batch production.
本发明公开了一种碳基复合材料接骨螺钉及其制备方法,该接骨螺钉包括螺帽和螺杆,接骨螺钉的基体由碳/碳/碳化硅复合材料构成,基体表面涂覆DLC涂层。接骨螺钉是利用碳纤维织物为原料,通过增密基体碳、机加工、增密基体碳化硅、高温处理及沉积DLC涂层等工艺步骤制成。该接骨螺钉具有轻质、生物相容性好、力学性能优异的特点,且制备过程简单、操作性强,有利于工业化批量生产。
