%X Corrosion behavior of BFe10-1-1 alloy in NaCl solutions was reported.The anode polarization curves of the alloy in the NaCl solutions with various pH values were measured by atomic absorption spectromepry(AAS).The concentrations of Cu~(2+) and Ni~(2+) in the solution were measured after corrosion test,and the corrosion layers were observed by SEM.The experimental results show that corrosion behavior of the BFe10-1-1 alloys in acidity NaCl solution was similar to that in mild alkaline solutions.It was found that because a stable passive film was formed on the alloy surface in pH=14(0.5 mol/L) NaCl solution,corrosion-resistance of BFe10-1-1 alloy at low potentials in strong alkaline solution was much better than that in acidity and mild alkaline solutions.When pitting corrosion occurred,the de-nickel corrosion occurred within the corrosion pits on the alloy.
