铅钙锡银合金电极行为的研究

摘要

This paper studied the inlfuences of silver on the corrosion behavior of lead-calcium alloy by the experiment of anode corrosion, cathode polarization and electrochemical impedance spectroscopy. The results showed that silver can signiifcantly improve the corrosion resistance, hydrogen evolution overpotential of lead-calcium-tin-aluminum alloy and the conductivity of corrosion layer.%本文通过阳极腐蚀、阴极极化和交流阻抗的实验研究了银对铅钙合金腐蚀行为的影响。实验结果表明，银可以显著提高铅钙锡铝四元合金的耐腐蚀性能、析氢过电位和腐蚀层的导电性能。
