Cored　wires　Fe-Cr-P-B-C　system　was　designed,　and　coatings　were　prepared　by　twin　wire　arc　spraying　on　Q235　substrate.　The　influence　law　on　microstructure,　wear　resistance　and　electrochemical　corrosion　resistance　of　coatings　with　phosphorus　were　investigated　by　X-ray　diffraction　(XRD),　scanning　electron　microscope　(SEM),　abrasive　wear　testing　machine,　and　electrochemical　workstation.　Results　showed　that　the　as-deposited　coatings　consisted　of　numerous　flattened　lamellae　parallel　to　the　substrate.　The　porosities　of　coatings　were　about　3%-4%.　The　coatings　were　amorphous/nanocrystalline　composite　coatings.　However,　the　partial　substitution　P　for　B　in　the　alloy　system　resulted　in　the　reduction　of　amorphous　content.　The　microhardness　and　wear　resistance　decreased　slightly　with　the　increase　of　x(P),　but　not　notable.　The　abrasive　wear　resistance　of　coatings　was　5-8　times　higher　than　that　of　the　Q235　substrate.　The　free　corrosion　potential　increased　after　adding　the　phosphorus　element　into　the　coatings,　which　was　beneficial　to　corrosion　resistance　of　coatings.　In　this　study,　the　coating　with　2%　phosphorus　addition　had　comparatively　better　wear　and　corrosion　resistance.
