Amorphous　Fe-(Cr,　Ni)-(C,　B)　coatings　were　prepared　on　low　carbon　steel　by　arc　spraying　technology.　The　phase　composition,　microstructure,　properties　of　thermal　stability　and　behavior　of　frictional　wear　were　studied　and　analyzed　by　X-ray　diffraction　instrument　(XRD),　scanning　electronic　microscope　(SEM),　differential　thermal　analyzer　and　MRH-3　friction　wear　testing　machine,　respectively.　The　results　showed　that　the　coating　had　a　high　content　of　amorphous　phase,　layered　distribution　and　a　dense　and　uniform　structure.　The　crystallization　process　in　the　coating　would　not　occur　at　the　temperature　below　500°C.　The　coating　possessed　high　hardness　and　excellent　friction　and　wear　properties,　with　the　average　hardness　of　1155　HV0.1.　At　the　same　experimental　conditions,　the　relative　wear-resistance　property　of　the　coating　was　13.3　times　of　the　one　of　Q235　steel,　the　wear　mechanism　was　mainly　dominated　by　fatigue　wear.
