从两相各自的阴极极化曲线如何判断是否可能有电偶腐蚀发生？如题。在读一篇文章的时候遇到的问题。文章是 A.J. Griffiths ‘an investigation of the electrochemical polarization behavior of 6061 aluminium metal matrix composites'. 文中比较了SiC和6061 Al各自的阴极极化曲线，得到结论说SiC/6061Al中不存在电偶腐蚀。求高人解答原理？在有氧条件下，原文描述如下：Comparison of figs 1 and 3 shows that the unreinforced Al alloy and the SiC supported similar cathodic current densities at a given potential in aerated solutions. therefore there is no basis for significant galvanic interaction between the SiC and the matrix alloy in the MMC. 图片在附件里了。。无氧条件下的原文描述：Comparison of figs 2 and 5 shows that the cathodic current densities at a given potential were more than an order of magnitude smaller for the SiC than for the unreinforced alloy in de-aerated solutions. therefore there is no galvanic interaction between the SiC and the Al alloy in a SiC/Al MMC in de-aerated conditions.原文也传上来了，麻烦高人解答！Fig1.jpgFig2.jpgFig3.jpgFig5.jpg查看更多5个回答 . 2人已关注
MgFe水滑石能否处理罗丹明B？A：0.6 M Mg(NO3)2?6H2O and 0.2 M Fe(NO3)3?9H2O为混合溶液，体积为100ml；B：1.2 M NaOH and 0.4 M Na2CO3 为混合溶液，体积为100ml，逐滴加入A于剧烈搅拌状态下的B中，直至悬浊液的pH为11，然后将其转移至烘箱中，80℃ 12h，冷却，水洗，离心3次，80℃干燥。由文献查的上述制备MgFe 水滑石 方法，用来处理 罗丹明 B，但结果没什么效果，不知道哪位大神做过类似实验，指教一下。1、不知道上述水滑石能否用来处理罗丹明B 2、上述方法是否有效? ???3、如果能应该怎么讨论。最好能给个确切方案。跪求指教！查看更多3个回答 . 3人已关注
