Abstract：

Through　adding　different　kinds　of　rare　earth　(RE)　compositions　and　moderate　amount　of　copper　constituent,　RE-Fe　based　alloy　coatings　were　prepared　by　thermal　spraying　(THSP).　The　corrosion　resistance　of　RE-Fe　based　alloy　coatings　with　different　compositions　and　post-spraying　treatments　were　investigated　systematically　by　maceration　corrosion　test,　electrochemical　test,　neutral　salt　spray　(NSS)　test　and　scanning　electron　microscopy.　The　results　show　that　the　addition　of　moderate　amount　of　rare-earth　compositions　and　copper　constituent　can　increase　remarkably　the　corrosion　resistance　of　iron-based　alloy　(Fe-Cr-Ni-B-Si)　coating　in　the　acid　and　salt　corrosion　media,　and　the　coating　with　2%　RE　oxide　composition　(mass　fraction)　possesses　the　best　comprehensive　effects.
