| 摘 要： | 采用电化学腐蚀实验和组织分析,研究合金元素Ni对ZA35合金在3.5%的NaCl溶液中电化学腐蚀行为的影响。结果表明:元素Ni能够细化晶粒,使粗大的树枝晶组织转变为团聚状组织,一次枝晶臂由细长变得短粗且圆整;加入质量分数为0.5%的Ni后,ZA35合金的显微组织得到细化,腐蚀电流密度降低,耐蚀性能得到明显改善。

| Abstract: | The effects of Ni on the electrochemical corrosion behavior of ZA35 alloy in 3.5% NaCl solution were studied by electrochemical corrosion tests and microstructure analysis.The results show that the element Ni can refine-grain and change thick-dendrite-microstructure into agglomerated microstructure.The primary elongated dendrite arm becomes short,thick-and round.The microstructure of ZA35 alloy can be refined after the addition of 0.5% Ni(mass fraction),the corrosion current density is reduced and the corro... |
