SELECTIVE CORROSION OF BFe10-1-1 ALLOY IN NaCl SOLUTION

Corrosion behavior of BFe10-1-1 alloy in 0.5mol/L NaCl solution was studied.The anodic polarization curves of the alloy in the NaCl solution at various pH values were measured.The corrosion behavior of the alloy at various potentials was investigated by means of measuring the concentrations of Cu2+ and Ni2+ in the corroding solution and characterizing the corrosion layers.The experimental results show that the selective corrosion of the BFe10-1-1 alloy was determined by the pH value and potential in the 0.5mol/L NaCl solution.
