Ni-Fe-C-Si　self-lubricating　alloy　was　prepared　by　melting　method.　The　effects　of　iron　content　on　the　mechanical,　dry　friction　and　oil　lubrication　friction　properties　were-investigated.　The　results　show　that　with　increasing　of　iron　content,　the　content　of　graphite　and　the　self-lubrication　of　the　alloy　increase,　the　impact　toughness　and　the　tensile　strength　decrease,　and　the　hardness　reduces　at　first　and　then　increases.　Both　the　coefficients　of　dry　friction　and　oil　lubrication　reduce　with　increasing　of　iron　content,　and　the　wear　rate　reduces　with　the　increasing　of　hardness　values.　The　dry　friction　coefficient　of　Ni-60Fe-3.5C-1Si　alloy　(mass　fraction,　%)　is　the　smallest,　and　the　dry　friction　and　oil　lubrication　coefficients　of　the　alloy　are　0.18　and　0.40,　respectively.
