A　series　of　Fe-xCr　cored　wires　(x　=　15,　20,　25,　30,　35　and　40%　in　weight)　were　used　to　produce　protective　coatings　for　components　used　in　high-temperature　environments　by　wire-arc　spraying.　The　microstructure,　morphology　and　high-temperature　oxidation　behavior　of　the　Fe-xCr　coatings　were　investigated.　The　Fe-xCr　coatings　presented　a　homogeneous　structure　with　thin　oxide　inclusions　and　low　porosity.　Thermogravimetric　analysis　was　used　to　evaluate　the　high-temperature　oxidation　behavior　of　the　coatings　at　a　temperature　of　650　degrees　C　under　cyclic　oxidation　conditions.　The　results　showed　that　all　the　Fe-xCr　coatings　exhibited　significantly　lower　weight　gain　than　the　uncoated　substrate.　As　Cr　content　of　the　coatings　increased,　the　thickness　of　oxide　scales　decreased　and　oxidation　resistance　improved.　(C)　2014　Elsevier　B.V.　All　rights　reserved.
