Fe-based　amorphous　alloy　coatings　were　prepared　on　mild　carbon　steel　substrate　by　arc　spraying.　Microstructure　and　properties　of　the　coatings　were　investigated　by　XRD,　SEM,　TEM　and　micro-hardness　test.　Wear　resistance　of　the　coatings　were　eximined　by　wet　sand/rubber　wheel　abrasive　wear　tester.　The　experiment　results　show　that　the　coating　has　laminated　microstructure　with　a　little　micro-pores　and　oxides.　The　coating　has　high　hardness　and　excellent　wear　resistance,　and　its　relatively　wear　resistance　is　15.2　times　of　mild　carbon　steel　in　the　same　experimental　condition.
