We　reported　the　current-carrying　friction　behavior　of　graphene　nanocrystallites　carbon　(GNC)　film,　which　had　hybrid　structure　with　graphene　nanocrystallites　embedded　in　amorphous　carbon　(a-C)　matrix.　The　GNC　film　exhibited　high　electrical　conductance　of　7.7　similar　to　30.9　S/cm　for　effective　current　transmission,　and　short　run-in　period　of　10　similar　to　25　frictional　cycles　for　achieving　low　friction　(mu　=　0.03　similar　to　0.05)　with　low　electric　power　of　0.25　similar　to　0.60　W　under　the　electric　current　of　0.5　A.　As　a　comparison,　a-C　film　showed　low　electrical　conductance　of　3.2　S/cm　and　long　run-in　period　of　50　frictional　cycles　with　high　electric　power　of　1.25　W.　The　high　electrical　conductance　and　the　short　run-in　period　effectively　reduce　the　electrical　and　mechanical　energy　consumption　for　the　GNC　film,　thus　presenting　wider　promising　practical　applications.　Based　on　the　nanostructure　characterization,　the　role　of　graphene　nanocrystallites　was　summarized　as　the　electron　transport　channels　for　transmitting　the　electric　current　and　the　source　of　graphene　nanocrystallite　structure　for　promoting　the　low　friction　interface　formation.　These　findings　present　potentials　of　the　GNC　film　in　protecting　the　current-carrying　friction　interface.
