The　corrosion-wear　behavior　of　Fe-3.5　wt.%B　steel　in　liquid　zinc　was　investigated　via　the　block-against-ring　technique.　Owing　to　the　protective　ability　of　the　Fe2B　phase,　this　steel　exhibited　better　corrosion-wear　resistance　than　a　316L　stainless　steel.　SEM,　XRD,　and　EDS　of　the　corrosion-wear　interface　indicated　that　the　corrosion-wear　process　of　Fe-3.5　wt.%B　steel　consists　of　the　following　steps:　corrosion　of　the　matrix,　fragmentation　and　removal　of　FeZn13,　and　failure　of　the　Fe2B.　The　intensified　mechanical　effect　of　wear　resulted　in　significant　deterioration　(via　fracture　and　removal　of　FeZn13,　and　spallation　Fe2B)　of　corrosion-wear　interface,　which　exacerbated　corrosion,　and　facilitated　the　corrosion-wear　process.
