模拟文物铸铁的阴极保护

Cathodic Protection of the Rusted Cast Iron

    摘要
  • 摘要: 在模拟的文物铸铁上,研究已生成较厚锈层的带锈铸铁在3.5%NaCl溶液中阴极保护的可能性和可行性,并确定最佳保护参数。结果表明,带锈铸铁的阴极保护是可行的;在本体系中最佳保护电位范围是-900~-1000mV(SCE);当保护电位比-1100mV(SCE)更负时,保护效率将显著降低。

     

    Abstract: Possibility and feasibility of cathodic protection(CP) on the rusted cast iron with thick rust layer and the optimum parameter of protection were studied. The results showed that it was feasible to protect rusted cast iron by cathodic protection technique.The optimum protection potential was between-900 mV and -1000 mV(SCE) under the present condition.If protection potential was more negative than-1100mV (SCE),the protection efficiency would dramatically drop.
