| 摘 要： | 应用扫描电镜、金相显微镜、晶间腐蚀试验、剥落腐蚀试验考察三种不同元素含量5083合金板材的腐蚀性能,在EXCO溶液中进行极化曲线测试.结果表明,合金的抗蚀性能和镁元素含量有很大的关系,5083合金板材的晶间腐蚀和剥落腐蚀倾向随镁含量的增加而增大.锰元素对腐蚀电位影响不大,但可提高抗晶间腐蚀及剥落腐蚀性能. |

| Abstract: | The corrosion property of 5083 aluminum alloy sheets with different contents of three elements is investigated by SEM,metallographic microscopy,intergranular corrosion test and exfoliation corrosion test.Polarization curves of these samples are measured in EXCO solution.It shows that the anti-corrosion property of alloy is relevant to the content of magnesium element,and the intergranular corrosion and exfoliation corrosion of the 5083 alloy sheet are increased with the increase of magnesium content.The con... |
