摘要(Abstract)：

为了改善增强相在Cf-Al_2O_3/Cu复合材料中的分布和结合,分别采用溶胶凝胶法和化学镀法对碳纤维(Cf)表面进行了镀TiO_2和Cu涂层处理,并采用粉末冶金法结合内氧化工艺制备Cf-Al_2O_3/Cu复合材料。采用X射线衍射仪(XRD)、扫描电镜、布氏硬度计和导电率测试等研究了纤维涂层对Cf-Al_2O_3/Cu复合材料组织和性能的影响。结果表明:Cf和Al_2O_3的添加提高了复合材料的硬度,但是致密度和导电率相对于纯铜有所下降。Cf表面涂层处理保护了粉末冶金过程中Cf的结构完整性,有利于Cf在铜基体中的均匀分布,所制备的复合材料的致密度和导电率相对于无涂层状态明显提高。其中,纤维表面化学镀Cu涂层厚度均匀且连续性较好,其制备的复合材料导电率达到80%IACS,相比于未处理的Cf-Al_2O_3/Cu复合材料提高了11.9%。
