The　effect　of　erosion　angle　on　erosion　behavior　of　the　as-cast　Fe-B　alloy　in　flowing　liquid　zinc　was　investigated.　The　results　show　that　the　erosion　rate　of　Fe-B　alloy　decreases　linearly　with　increasing　erosion　angle.　The　erosion　resistance　of　Fe-B　alloy　is　better　than　that　of　316L　stainless　steel,　which　is　attributed　to　the　favorable　barrier　effect　of　net-like　Fe2B　that　resists　erosion　by　flowing　liquid　zinc.　Meanwhile,　the　ductile　matrix　can　provide　support　in　preventing　borides　from　spalling　and　borides　cause　barrier　effect　on　flowing　liquid　zinc　during　liquid　zinc　erosion,　which　shows　a　synergistic　erosion-corrosion　behavior　between　the　matrix　and　borides.　Moreover,　an　increase　in　erosion　angle　can　cause　a　decrease　in　the　removal　effect　of　the　flowing　liquid　zinc　scouring　component　on　the　erosion　compounds.　Therefore,　the　quantity　of　erosion　compounds　increases　at　the　erosion　interface,　weakening　the　mass　transfer　process　and　decreasing　the　erosion　rate　of　the　Fe-B　alloy.　(C)　The　Minerals,　Metals　&　Materials　Society　and　ASM　International　2015
