| 目的 研究在铝合金样品表面制备Ag掺杂类石墨薄膜对样品导电、耐蚀性能的影响。方法 采用磁控溅射离子镀技术，在6061铝合金表面沉积了Ag掺杂类石墨层，对样品微观形貌、接触电阻和电化学腐蚀性能进行了观察测试。结果 类石墨薄膜厚度随着Ag靶电流的提高而增大。与铝合金基体相比，镀膜样品的接触电阻降低了2个数量级，腐蚀电流密度降低了2~3个数量级。Ag靶材电流为0.04 A时，镀膜样品接触电阻（1.5 MPa压强）为1.93 mΩ•cm2，腐蚀电流密度低至105.5 A/cm2数量级。结论 沉积有Ag掺杂类石墨薄膜的样品达到了极低的表面接触电阻与较低的腐蚀电流密度，使镀膜后的铝合金样品具有优异的导电性能与较好的耐腐蚀性能。 |

| The work aims to study effects of preparing Ag-doped graphite-like films on aluminum alloy samples on conductivity and corrosion resistance of the samples. Different Ag-doped graphite-like films were deposited on 6061 aluminum alloy bipolar by adopting magnetron sputtering ion plating technology. Microstructure, contact resistance and electrochemical corrosion resistance of the samples were observed and tested. Thickness of graphite-like films increased as Ag target current increased. ICR (interfacial contact resistance) of the coated samples decreased by 2 orders of magnitude, and corrosion current density decreased by 2~3 or-ders of magnitude compared with that of uncoated samples. When Ag target current was 0.04 A, the ICR (1.5 MPa) of the coated samples reached 1.93 mΩ•cm2 and the corrosion current density reached 105.5 A/cm2. The samples deposited with Ag-doped graphite-like films exhibit extremely low ICR and lower corrosion current density, endowing the coated samples with excellent conductivity and better corrosion resistance. |
