| 摘 要： | 以碳纳米管(CNTs)、碳化硅(SiC)粉体、锌(Zn)粉和CuSO_4·5H_2O为主要原料,用化学镀的方法制备CNTs /Cu复合粉体,再采用非均相沉淀法制备CNTs/SiC/Cu复合粉体.在750 ℃、100 MPa的制度下进行真空热压烧结后制得CNTs/SiC/Cu复合材料,其中Cu的含量(体积分数,下同)为70%,CNTs的含量(体积分数, 下同)分别为0,3%,5%,8%,12%.利用XRD、SEM分析样品的物相组成和显微结构;利用阿基米德排水法、显微硬度计、三点弯曲法测试了复合材料的密度、显微硬度和抗弯强度.结果表明,随着碳纳米管含量的增加,CNTs/SiC/Cu复合材料的密度、显微硬度和抗弯强度等性能发生相应变化,其中,抗弯强度呈现逐渐升高趋势.与未添加碳纳米管的30SiC/70Cu复合材料相比,添加12%CNTs的12CNTs/18SiC/70Cu 样品,抗弯强度提高了21.45 MPa.

| Abstract: | Using carbon nanotubes (CNTs),silicon carbide (SiC) powders,zinc (Zn) powders and CuSO4.5H2O as the main raw materials,the CNTs /Cu composite powders were prepared by the chemical plating method,and the CNTs /SiC/Cu composite powders were prepared by heterogeneous deposition method. The CNTs/SiC/Cu composites were prepared by vacuum hot pressing under the condition of 750 oC and 100 MPa. These composites samples consist of Cu (70%),CNTs (0,3%,5%,8% and 12%) and SiC powders (30%,27%,25 %,22% and 18%),respect... |
