| 摘 要： | 采用腐蚀失重法和极化曲线，对比研究了FVS0611，FVS0812，2618，2618 Sc，2014，6061合金在人工模拟海水和海洋环境中的耐蚀性能。结果表明：2014，2618和2618 Sc腐蚀较严重；RS／PM生产的FVS0611，FVS0812和6061有较小的腐蚀速率，出现明显的钝化现象；并因为加工残余应力导致出现钝化-腐蚀-再钝化现象。

| Abstract: | Through corrosion weight-losing and polarization curve test, the corrosion-resistance properties of FVS0611, FVS0812, 6061, 2618, 2618+Sc, 2014 alloys under artificial seawater and oceanic condition have been investigated. It shows that FVS0611, FVS0812 and 6061 alloys prepared by RS/PM have a low corrosion while 2618, 2618+Sc and 2014 alloys has high corrosion. FVS0611, FVS0812 and 6061 alloys have obvious passivation. In the meantime, a phenomenon of passivation-corrosion-passivation occurs among them because residual process stress exists |
