A　coating　with　high　hardness,　wear　and　oxidation　resistance　was　prepared　by　electric　arc　spray.　The　hardness,　bonding　strength,　abrasive　wear　and　values　of　porosity　and　oxidation　resistance　of　the　coating　were　investigated.　The　microstructures　and　function　of　Cr3C2　of　the　coating　were　analyzed.　The　results　showed　surface　Rockness　Hardness　HR30　reached　72.5　and　average　bond　strength　reached　49.1Mpa.　Also　porosity　value　was　less　than　2%.　In　addition,　it　was　found　from　the　comparison　between　the　coating　and　45CT　coating　that,　oxidation　resistance　of　the　coating　was　less　than　that　of　45CT,　but　the　abrasive　wear　of　the　coating　was　obvious　better　than　that　of　45CT.
