对镍含量为0 ~ 30%、铁含量< 0.05 ~ 2%的Cu-Ni-Fe合金的海水腐蚀研究表明，这些铜合金中的镍和铁具有协同作用。这种效应在低速海水和射流冲击试验等腐蚀数据以及内腐蚀产物层的组成中都很明显。镍有利于铜的耐蚀性，但合金中铁的存在大大增强了它的作用。产生这种效应的原因显然与材料表面的镍富集有关，但铁刺激镍富集的机制目前还不确定。
Abstract Sea water corrosion studies on Cu-Ni-Fe alloys ranging in nickel content from 0 to 30% and iron content from <C0.05 to 2% have demonstrated a synergistic effect between nickel and iron in these copper alloys. This effect is apparent in corrosion data such as low velocity sea water and jet impingement tests, as well as the composition of inner corrosion product layer. Nickel is beneficial to the corrosion resistance of copper, but its effect is greatly enhanced by the presence of iron in the alloy. The reason for this effect is apparently tied to nickel enrichment of the material surface, but the mechanism of iron stimulation of nickel enrichment is undetermined at present.
