To　improve　the　heat　transfer　ability　and　wear　resistance　of　drying　cylinders　in　paper　production　machines,　a　series　of　Fe87-x　Cr13B　(x)　(x　=　1　wt.%,　1.5　wt.%,　2　wt.%,　2.5　wt.%,　3　wt.%,　and　4　wt.%)　cored　wires　have　been　produced　and　used　to　prepare　coatings　by　wire-arc　spraying,　in　comparison　with　conventional　X30Cr13　solid　wire.　All　coatings　presented　dense　layered　structure　with　porosity　of　around　4%.　The　boron　content　in　the　cored　wires　significantly　affected　the　thermal　conductivity　of　the　coating,　which　is　attributed　to　the　combined　effects　of　the　crystal　structure,　grain　size,　and　oxide　content　of　the　coating.　In　the　investigated　range,　the　coating　with　2　wt.%　boron　content　exhibited　the　highest　thermal　conductivity,　reaching　8.83　W/m-K,　greater　than　that　of　X30Cr13　coating　(5.45　W/m-K).　Furthermore,　the　microhardness　and　relative　wear　resistance　of　the　FeCrB　coatings　obtained　from　cored　wires　with　boron　addition　were　greatly　increased　compared　with　commercial　X30Cr13　coating.　Therefore,　wire-arc-sprayed　FeCrB　coating　has　promise　as　an　effective　and　economic　approach　to　improve　the　heat　transfer　behavior　and　wear　resistance　of　drying　cylinders　in　the　paper　industry.
