    摘要:

    核電用冷凝器的失效形式以腐蝕為主,本文利用電化學(xué)測試系統(tǒng)、XRD、OM、SEM和EDS等分析測試方法研究Cu-30Ni-xRE(x=0~0.213)合金耐腐蝕性能及其機(jī)理,結(jié)果表明,與不含稀土的Cu-30Ni合金相比,適量稀土添加的Cu-30Ni-0.095RE合金的Ni元素偏析降低,枝晶和晶間腐蝕驅(qū)動(dòng)力減小,導(dǎo)致腐蝕電位提高約11.0%,腐蝕電流密度iC降低約37.3%。

    Abstract:

    The mechanism of corrosion resistance for Cu-30Ni-xRE(x=0~0.213) alloy were investigated by employing electrochemical testing, x-ray diffraction, optical microscopy, scanning electrical microscopy and Energy Disperse Spectroscopy. The results showed that comparison with Cu-30Ni alloy without RE, Cu-30Ni-0.095RE alloy with right amount had decreasing composition segregation of Ni element. This resulted in the decease of corrosion driving force between centre of dendrite and interdendritic. As a result, for Cu-30Ni-0.095RE alloy the corrosion potential increased by 11.0%, and the corrosion current decreased by 37.3%.
