Fe-based　amorphous　coatings　were　prepared　on　mild　carbon　steel　substrate　by　arc　spraying.　Microstructure　and　properties　of　coatings　were　investigated　by　XRD,　SEM,　TEM　and　micro-hardness　meter,　and　wear　resistance　of　coatings　was　investigated　by　wet　sand/rubber　wheel　abrasive　wear　tester.　The　experiment　results　show　that　the　coating　has　homogenous　laminated　microstructure　and　contains　only　a　little　micro-pores　and　oxides.　The　coating　has　high　hardness　and　wear　resistance.　The　microhardness　is　between　900-1000　HV100g,　and　the　relatively　wear　resistance　is　13　times　than　Q235　steel　under　the　same　experimental　condition.
