中文摘要:
      采用机械合金化技术将不同用量的CuO或Fe2O3粉掺入银和SnO2粉中制备Ag/SnO2(x)-MeO(y)复合粉体,并辅以热压成型工艺制得Ag/SnO2(x)-MeO(y)电接触材料。采用扫描电镜、X射线衍射仪、电阻测试仪、硬度计及拉伸试验机等测试仪器对材料的组织结构、物理和力学性能进行了表征。结果表明:随着掺杂剂用量的增加,Ag/SnO2(x)-MeO(y)材料的密度逐渐降低,且CuO较Fe2O3更利于提高材料的导电性。两种掺杂剂均能显著改善Ag/SnO2(x)-MeO(y)材料的塑性变形能力。Ag/SnO2(11.2%)-CuO(0.8%) (也即CuO用量为0.8%)材料的电阻率达到最低值2.35 μΩ.cm,延伸率约为9.1%,比Ag/SnO2材料的延伸率提高近93.6%,综合性能最优。
Microstructure and Properties of MeO Doped Ag/SnO2 Electric Contact Materials

英文摘要:
      Ag/SnO2(x)-MeO(y) composite powders were obtained by means of mechanical alloying different contents of CuO or Fe2O3 powders with Ag and SnO2 powders, and Ag/SnO2(x)-MeO(y) electrical contact materials were prepared by hot pressing process. The microstructure and physical and mechanical properties of the materials were characterized by scanning electron microscopy, X-ray diffractometry, resistance tester, hardness tester and tensile tester. The results show that the density of Ag/SnO2(x)-MeO(y) materials decreases with the increase of dopant content, and CuO is more conducive to improving the conductivity of Ag/SnO2(x)-MeO(y) material than Fe2O3. The two dopants can obviously improve the capacity of plastic deformation of Ag/SnO2(x)-MeO(y) material. The Ag/SnO2(11.2%)-CuO(0.8%) material (i.e. CuO content =0.8%) exhibits the best comprehensive properties with the resistivity about 2.35 μΩ?cm, elongation about 9.1% (higher than that of Ag/SnO2 material by 93.6%).
