摘 要: 采用直流磁控溅射法制备了银涂层，用XRD分析了银涂层的组织结构；制备了加入聚苯胺(PANI)作为导电
润滑添加剂的聚苯胺润滑脂，利用载流摩擦磨损试验机(HFT-4000)评价了银涂层的摩擦和导电性能. 利用扫描电镜
(SEM)和能谱仪(EDS)分析评价了磨损表面. 结果表明：与商品导电润滑脂相比，聚苯胺润滑脂比商用导电润滑脂具
有更好的润滑性能和低电阻，同时磁控溅射镀银层比电镀银层具有更好的摩擦学性能和导电性能，其原因归结为
电流诱导的热效应和聚苯胺润滑脂在摩擦副表面的摩擦化学效应共同作用的结果.

Abstract: The silver coating was prepared by DC magnetron sputtering, the structure of silver coating was analyzed by
X-ray diffraction. Polyaniline grease was prepared with polyaniline (PANI) as a conductive lubricant additive, and the
friction and conductivity of silver coating were evaluated by using a current carrying friction and wear tester (HFT-4000).
The worn surface was evaluated by scanning electron microscopy(SEM) and energy dispersive spectroscopy(EDS). The
results showed that PANI grease had better lubricity and lower resistance than commercial conductive grease, and the
silver coating by magnetron sputtering had better tribological and conductive properties than that by silver plating. The
reason was due to the combined effect of current induced thermal effect and the tribochemical effect of PANI grease on
the surface of friction pair.
Key words: magnetron sputtering silver coating; electrotribological properties; electrically conductive grease; current
carrying lubrication; resistance
