抄録

The influencing factors on galvanic corrosion were reviewed briefly on the basis of an electrochemical equivalent circuit. Electrochemical circuit is formed when two different metals immersed in a common electrolyte come into electric contact. Anodic current density on a less noble metal (anode) is a function of potential difference, apparent anodic polarization resistance, apparent cathodic polarization resistance, solution resistance, contact resistance, anode area and its ratio to cathode area. Galvanic corrosion can be prevented by keeping at least one of these resistance values higher that 10⁵Ωcm², preferably of contact resistance. Smaller cathode area is recommended while smaller anode area should be avoided.
