| 中文摘要 | polyaniline emeraldine base/epoxy resin (eb/er) coating was investigated for corrosion protection of mild steel coupled with copper in 3.5% nacl solution. eb/er coating with 5-10 wt% eb had long-term corrosion resistance on both uncoupled steel and copper due to the passivation effect of eb on the metal surfaces. during the 150 immersion days, the impedance at 0.1 hz for the coating increased in the first 1-40 days and subsequently remained constant above 10(9) omega cm(2), whereas that for pure er coating fell below 10(6) omega cm(2) after only 30 or 40 days. immersion tests on coated steel-copper galvanic couple showed that eb/er coating offered 100 times more protection than er coating against steel dissolution and coating delamination on copper, which was mainly attributed to the passive metal oxide films formed by eb blocking both the anodic and cathodic reactions. salt spray tests showed that 100 mu m eb/er coating protected steel-copper couple for at least 2000 h. |
