The　effects　of　0.3　wt.%　Al　added　to　flowing　liquid　zinc　on　the　corrosion　inhibition　and　erosion-corrosion　interfacial　characteristics　of　Fe-3.5　wt.%　B　alloy　were　investigated　in　order　to　separate　the　pure　erosion　rate　from　the　total　erosion-corrosion　rate　and　further　study　the　erosion-corrosion　interaction　created　by　flowing　zinc.　The　result　indicated　that　the　erosion-corrosion　rate　increased　slowly　and　then　sharply　thereafter,　while　the　corrosion-inhibition　rate　increased　linearly　and　slowly　at　a　bath　temperature　of　460550　degrees　C.　The　corrosion-inhibition　efficiency　of　0.3　wt.%　Al　addition　in　the　flowing　liquid　zinc　bath　was　significantly　reduced　and　then　enhanced　with　increasing　bath　temperatures,　depending　on　the　interfacial　microstructures　after　Al-corrosion　inhibition.　A　uniform　and　continuous　Fe(2)Al(5)Znx　inhibition　layer,　which　suppressed　the　corrosion　reaction　of　iron　and　zinc,　formed　on　the　erosion-corrosion　interface　of　the　Fe-3.5　wt.%　B　alloy,　thereby　reducing　the　spallation　of　anticaustic　Fe2B　skeleton.　Moreover,　the　gradual　deterioration　of　the　inhibition　layer　led　to　a　reduction　in　the　corrosion-inhibition　ability.　The　present　results　indicate　that,　due　to　the　beneficial　Al-corrosion　inhibition　effect,　the　corrosion-inhibition　rate　as　the　pure　erosion　rate　of　Fe-3.5　wt.%　B　in　flowing　liquid　zinc　can　be　well　separated　from　the　erosion-corrosion　rate　by　adding　0.3　wt.%　Al　to　flowing　liquid　zinc　bath.
