| 摘 要： | 利用电化学阻抗谱（EIS）技术,研究了浸泡在3.5%NaCl溶液中的SrCrO4环氧涂层、纳米ZnO环氧涂层、纳米缓蚀剂插层水滑石环氧涂层和ZnO/纳米水滑石复合环氧涂层的防腐性能。结果表明,纳米缓蚀剂插层水滑石涂层对Mg-Li合金的防腐效果明显高于SrCrO4环氧涂层和纳米ZnO环氧涂层,具有活性-自修复的防腐作用;而经过改性的原位生成ZnO纳米水滑石复合涂层的防腐性能更好。

| Abstract: | Anticorrosion performance of four kinds of coatings：the epoxy resin coatings filled with SrCrO4,nano-ZnO,inhibitor intercalated hydrotalcite nano-compounds and ZnO/hydrotalcite nanocomposite as pigments immersing in the 3.5% NaCl solution,was comparatively investigated by means of electrochemical impedance spectroscopy（EIS） measurement.The results showed that the inhibitor intercalated hydrotalcite nano-compounds coating owning self-sealing function showed better corrosion resistance than the SrCrO4 and nano-ZnO coatings.However,the ZnO/hydrotalcite nanocomposite coatings showed the best corrosion resistance,which may be owed to the beneficial effect induced by the treatment with in situ created ZnO. |
