    摘要:

    采用機(jī)械合金化技術(shù)將不同用量的CuO或Fe2O3粉摻入銀和SnO2粉中制備Ag/SnO2(x)-MeO(y)復(fù)合粉體,并輔以熱壓成型工藝制得Ag/SnO2(x)-MeO(y)電接觸材料。采用掃描電鏡、X射線(xiàn)衍射儀、電阻測(cè)試儀、硬度計(jì)及拉伸試驗(yàn)機(jī)等測(cè)試儀器對(duì)材料的組織結(jié)構(gòu)、物理和力學(xué)性能進(jìn)行了表征。結(jié)果表明：隨著摻雜劑用量的增加,Ag/SnO2(x)-MeO(y)材料的密度逐漸降低,且CuO較Fe2O3更利于提高材料的導(dǎo)電性。兩種摻雜劑均能顯著改善Ag/SnO2(x)-MeO(y)材料的塑性變形能力。Ag/SnO2(11.2%)-CuO(0.8%) (也即CuO用量為0.8%)材料的電阻率達(dá)到最低值2.35 μΩ.cm,延伸率約為9.1%,比Ag/SnO2材料的延伸率提高近93.6%,綜合性能最優(yōu)。

    Abstract:

    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%).
