%X Potentiodynamic scanning methods and cycle voltammetry (CV) technique were employed to study the electrochemical behavior of archaeological bronze in a medium (0.028 mol/L NaCl+0.01 mol/L Na_2SO_4+0.016 mol/L NaHCO_3) simulating atmosphere corrosion.The study focused on the protection performance provided by CuCl,Cu_2O,Cu_2(OH)_3Cl and mixed patina to bare bronze,and the results are that when the corrosion potentials are relatively negative,CuCl and Cu_2O respectively exibibit to be protective to bare bronze to certain extent,and they perform more effective than that of Cu_2(OH)_3Cl or mixed patina's.On the other hand when the corrosion potentials are relatively positive the protectiveness of CuCl or Cu_2O to bare bronze turn to poor and Cu_2(OH)_3Cl or mixed patina exhibit better protective to bare bronze than that of CuCl or Cu_2O.The 0.1%MBO (2-Mercaptobenzoxazole) alcohol solution can suppress anodic reactons of bare bronze or bronze covered with CuCl or Cu_2O to some extent and can obviovsly suppress that of bronze covered with Cu_2(OH)_3Cl or mixed patina.
