【摘要】 研究了铜碲锂多元合金中碲对合金耐腐蚀性的影响。经过25℃在 3.5% NaCl溶液中的全浸试验表明铜碲锂多元合金比纯铜具有更好的耐蚀性。利用扫描电镜观察腐蚀试样的表面形貌,发现表面不均匀的覆盖着一层多孔的腐蚀产物。经 X 射线衍射仪分析确定,该腐蚀产物为 Cu2 (OH)3Cl 和 Cu2O 的混合物。更多还原

【Abstract】 The influence of Te and the third composition to the corrosion-resistance of copper alloys is investigated. After immersion in the 3.5% sodium chlorine （NaCl） solution at 25℃,Cu-Te alloys show better corrosion-resistance than pure copper. Observing the samples′ morphologies by SEM, it was found that the surface was covered by porous corrosion products. Cu₂（OH）₃Cl and Cu₂O was determined by the analysis of XRD.更多还原
