为探讨干摩擦磨损条件下含石墨转移层对摩擦磨损性能的影响，在45＃钢表面覆盖含石墨润滑层，通过干滑动磨损试验，研究含石墨润滑层对钢／铜－二氧化硅摩擦副摩擦因数、磨损量及摩擦损（亚）表面的影响。结果表明：与无石墨润滑层的45＃钢相比，含石墨润滑层的45＃钢的摩擦因数、磨损率明显下降，且干滑动试验后磨损表面相对光滑平整，表明含石墨摩擦层起到了减摩降磨作用，抑制了金属的直接接触。
為探討榦摩抆磨損條件下含石墨轉移層對摩抆磨損性能的影響，在45＃鋼錶麵覆蓋含石墨潤滑層，通過榦滑動磨損試驗，研究含石墨潤滑層對鋼／銅－二氧化硅摩抆副摩抆因數、磨損量及摩抆損（亞）錶麵的影響。結果錶明：與無石墨潤滑層的45＃鋼相比，含石墨潤滑層的45＃鋼的摩抆因數、磨損率明顯下降，且榦滑動試驗後磨損錶麵相對光滑平整，錶明含石墨摩抆層起到瞭減摩降磨作用，抑製瞭金屬的直接接觸。

In order to investigate the effect of graphite?contained transfer layer on the dry friction and wear behavior of materials, a graphite?contained layer was prepared on the frictional surfaces of 45 steel. The effects of graphite?contained layer on friction coefficient, wear loss and morphologies of worn ( sub) surface were studied by dry sliding test of 45 steel with a graphite layer against Cu?SiO2 . The results show that, compared with the 45 steel, the 45 steel with a graphite layer has lower friction coefficient and wear loss, and the worn surface of 45 steel is relatively smooth. The graphite?contained layer plays a role in friction reducing and anti?wear during the dry sliding process, which prevents the direct contact of metal friction pairs.
