High　hardness　and　wear　resistance　coating　JCW-B　were　deposited　via　arc　spraying.　The　microstructure,　porosity,　hardness,　bond　strength　and　abrasion　behavior　of　JCW-B　coating　was　analyzed,　the　erosion　resistance　properties　of　coating　was　compared　with　Arc　Spray　Welded　Ni60　coating.　Results　showed　that　JCW-B　coating　exhibited　dense　microstructure,　low　porosity,　high　hardness,　high　bond　strength　and　excellent　abrasive　and　erosive　wear　resistance.　XRD　spectrum　of　the　coatings　indicates　that　Fe3B　was　contained　as　the　main　hard　phase,　which　dispersedly　strengthens　the　coatings.　Moreover,　some　Fe2O3,　FeO　were　also　formed　during　the　spraying　process.　It　was　concluded　that　FeB3　randomly　distributed　in　the　microstructure　of　coating　act　as　hard　phase　promoting　wear　properties.
